Answer 1

slope = 8

Explanation:

calculate the slope m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (- 3, - 8) and (x₂, y₂ ) = (2, 32) ← 2 ordered pairs from the table

note any pair of ordered pairs will give the slope

m =
`(32-(-8))/(2-(-3))` =
`(32+8)/(2+3)` =
`(40)/(5)` = 8
