Question

Find the slope of the line passing through the points , (−7,2) and , (9,6) .

Answer 1

6-2 = 4

9- -7 =16

4/16 = 1/4

slope = 1/4

Answer 2

slope of the line is 

y₂ - y₁
------- = slope
x₂ - x₁

choose one as your "2" & the other as your "1" Plug them in
6 - 2
------
9 - (-7)

4/16
simplify the fraction
4/16 = 1/4

the slope is 1/4

hope this helps
