Question

What is the slope-intercept equation for the line below?

Answer 1

y = 5/4x - 4

Explanation:

First, find the slope by doing change in y/change in x

You have the points (4, 1) and (0, -4), so the slope would be:

-4 - 1 / 0 - 4 = -5 / -4 = 5/4

Then, find the y-intercept

It gives you that the y-intercept is (0, -4).

Now put the equation in the form y = mx + b where m is the slope and b is the y-intercept.

You have that m = 5/4 and b = -4, so it would be y = 5/4x - 4.
