How do you graph ?
,
Where,
m = slope
b = y-intercept
Now calculate x and y-intercept
The x-intercept is the value of x and y = 0. and the y-intercept is the value of y when x = 0.
the y-intercept in the given equation is 0, and the point is (0,0).
To determine the x-intercept, substitute 0 for y and solve for x.
Divide both sides by -2.
The x-intercept is 0 and the point is (0,0)
Plot the x and y-intercept and draw a straight line through them.

Part A
Suppose that you want to construct a line with slope that passes through . You would begin by setting up the equation . If you plug in the coordinates for any point on that line, the two sides of the equation will be equal. Once you've done this, you can solve for . What is the value of ?
Part B
Suppose that you want to find the equation for a line that passes through the two points and . What is the slope of this line?
Part C
Now, that you have the slope, proceed as you did in Part A. What is the value of for this line?
Part D
Now, find the equation for a line that passes through two points and . Express your answer in terms of .
