Question

find the slope of the line that passes through each pair of points : (-2,-8) ,(1,4)

Answer 1

The slope is defined as \[m = \frac{y-y _{1}}{x-x _{1}}\]

Now I hope you can calculate yourself :)

Answer 2

slope = [4-(-8)] 12 4
------- = ----- =
[1-(-2)] 3

Answer 3

the slope of the line that passes through each pair of points =4
