Question

Find the slope of the line that goes through the given points.
(-3,-2) and (– 15,13)

Answer 1

Answer:

Slope m=
`-(5)/(4)`

As a decimal:

m = -1.25

Explanation:

`m=(Rise)/(Run) =(y)/(x) \\m=(y2-y1)/(x2-x1) \\m=(13--2)/(-15--3) \\m=(15)/(-12) \\m=-(5)/(4)`

Answer 2

The equation for the slope of a line is (y2 - y1)/(x2 - x1). Using this we get:

(13 - -2)/(-15 - -3) = (13 + 2)/(-15 + 3) = 15/-12 = -5/4 (after simplifying by dividing by 3).

So your answer is -5/4
