Equation of a Straight Line
Solve 3x-y-1 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3x-y-1 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 1/-1 so this line "cuts" the y axis at y=
y-intercept = 1/-1 =Calculate the X-Intercept :
When y = 0 the value of x is 1/3 Our line therefore "cuts" the x axis at x=
x-intercept = 1/3 =Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is and for x=, the value of y is So, for a change of in x (The change in x is sometimes referred to as "RUN") we get a change of - () = in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 3Geometric figure: Straight Line
- Slope = 3
- x-intercept = 1/3 =
- y-intercept = 1/-1 =
Here we will show you how to calculate and provide solutions to math problems related to 6x - 2y = 2.
We will start by calculating and showing you the solution for the x-intercept and y-intercept of 6x - 2y = 2.
Then, we will show you how to get the graph plot coordinates for 6x - 2y = 2 so we can illustrate it on a graph.
Finally, we will solve 6x - 2y = 2 for x and also for y, then calculate and show you the solution for the slope of 6x - 2y = 2.
Find x-intercept
The x-intercept is where the graph crosses the x-axis. To find the x-intercept, we set y1=0 and then solve for x.
6x - 2y = 2
6x - 2(0) = 2
x1 = y1 = 0
Find y-intercept
The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.
6x - 2y = 2
6(0) - 2y = 2
y2 = -1 x2 = 0
Get Graph Plot Coordinates
Getting two graph points will allow you to make a straight line on a graph. The plot coordinate format is (x1,y1) and (x2,y2).
Thus, we use the x-intercept and y-intercept results above to get the graph plots for 6x - 2y = 2 as follows:
(x1,y1) and (x2,y2)
(,0)and (0,-1)
Solve for x
To solve for x, we solve the equation so the variable x is by itself on the left side:
6x - 2y = 2
x = y +
Solve for y
To solve for y, we solve the equation so the variable y is by itself on the left side:
6x - 2y = 2
y = 3x - 1
Find slope
The slope of the line (m) is the steepness of the line. It is the change in the y coordinate divided by the corresponding change in the x coordinate. Simply plug in the coordinates from above and solve for m to get the slope for 6x - 2y = 2
m = (y2- y1)/(x2- x1)
m = (-1 - 0)/(0 - )
m =

The Graph of The Following System of Equations is −2x + y = 3 and 4x + 2y = 2. Solve this using the graph.
An equation of degree 1 is called linear equations. The standard form of linear equations in two variables is ax + by = c, where a, b and c are constants.
Answer: The solution for the system of linear equations -2x + y = 3 and 4x + 2y = 2 is (x, y) = (, 2)
Let's solve the system of linear equations in two variables.
Explanation:
The given equations are -2x + y = 3 (1) and 4x + 2y = 2 (2)
From the graph, it is clear that the intersecting point of the given two linear equations is (, 2). So, this is the solution of the given system of equations.
Let's solve the equations algebraically.
From equation (2), we get
4x + 2y = 2
x = (2 - 2y) / 4
To solve the system of linear equations, we will substitute value of x = (2 - 2y) / 4 in equation (1) and solve for x.
⇒ -2((2 - 2y) / 4) + y = 3
⇒ -4 + 4y + 4y = 12
⇒ 8y = 12 + 4
⇒ 8y = 16
⇒ y = 2
Put y = 1 in equation (2).
⇒ x = (2 - 2(2))/4 = (2 - 4)/4 = -2/4
⇒ x =
We can use Cuemath's online system of equations calculator to solve the equations.
Thus, the solution for the system of linear equations is (x, y) = (, 2)
Complete step by step solution:
Given, \[3x + 2y = 2\].
To find the x-intercept. That is the value of ‘x’ at\[y = 0\]. Substituting this in the given equation. We have,
\[3x + 2(0) = 2\]
\[3x = 2\]
Divide by 3 on both sides of the equation,
\[x = \dfrac{2}{3}\]
\[x = \].
Rounding off the decimal number we have,
\[ \Rightarrow x = \]
Thus we have a coordinate of the equation which lies on the line of x-axis. The coordinate is \[(,0)\].
To find the y-intercept. That is the value of ‘y’ at \[x = 0\]. Substituting this in the given equation we have,
\[3(0) + 2y = 2\]
\[2y = 2\].
Divide by 3 on both sides of the equation,
\[y = \dfrac{2}{2}\]
\[ \Rightarrow y = 1\]
Thus we have a coordinate of the equation which lies on the line of the y-axis. The coordinate is \[(0,1)\].
Thus we have the coordinates \[(,0)\] and \[(0,1)\].
Let’s plot a graph for this coordinates,
We take scale
x-axis= 1 unit = units
y-axis= 1 unit = units
All we did was expand the line touching the coordinates \[(,0)\] and \[(0,1)\] by a straight line.
Without calculation we have found out one more coordinate is \[(,),(,)\] and \[(,)\]
Note: Intercept method is an easy method for drawing graphs. A graph shows the relation between two variable quantities, it contains two axes perpendicular to each other namely the x-axis and the y-axis. Each variable is measured along one of the axes. In the question, we are given one linear equation containing two variables namely x and y, x is measured along the x-axis and y is measured along the y-axis while tracing the given equations.

It was already hot in the steam rooms and Natasha sat down on the bottom step, it was hard to stand. She began to massage my legs, rising higher to my ass. She ran her fingers gently along the inner thighs. I slightly deliberately set my legs apart.

I was on the verge of orgasm, and so I continued to fuck her in the doorway. I lifted her in my arms, though hard, but began to fuck her in every way. - the moaning granny shouted.

After a few minutes we switched places. However, I didn't like fucking in the ass, so I got up and put my dick in my mom's mouth, while Kim returned. To her ass. At the same time, my mother was not at all embarrassed that I pulled a dick out of her ass in front of eKim. She grabbed my entire cock, pushing it down my throat.
