Question

What is an equation of the line that passes through the points (-3, 8) and (-2, 3)?

Answer 1

y = -5x - 7

Explanation:

(Change in y) / (Change in x)

(3-8) / (-2 - (-3))

-5 / 1

-5 is the slope

So far we have y = -5x

Plug in a set of values and find the difference

3 = -5(-2)

3 = 10

This is false

We need to subtract 7

Our equation therefore is

y = -5x - 7
