Question

How to find the slope of the line that passes through the points (−2,3) and (5,−7)

Answer 1

`(-10)/(7)`

Explanation:

Use the formula

m=
`(y2-y1)/(x2-x1)`

another way to say this is Δy divided by Δx

Δ means "change in"

m = slope

The y2 value is -7

The y1 value is 3

The x2 value is 5

The x1 value is -2

Plug those values in the formula

m =
`((-7)-3)/(5-(-2))`

Simplify

m =
`(-10)/(7)`

The slope is
`(-10)/(7)`
