Question 51248: Please help: Determine the equation of the line that has a slope of 4 and passes through the point (2,8). Write the equation in slope intercept form
Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
Write the equation in slope-intercept form:

You are given the slope, m = 4, so you can write:
Now you need to find the value of b, the y-intercept. This is easily done because you were also given a point (2, 8) through which the line passes.
So you substitute the (x, y) of the given popint (2, 8) into the equation and solve for b.
Simplify.
Subtract 8 from both sides of the equation.
So b = 0. Now you can write the final equation of the line whose slope is 4 and which passes through the point (2, 8).

Just out of curiosity, let's see what that looks like on a graph:
