Question

X-2, -1, 0, 1, 2
y -13, -9, -5, -1, 3
What is the slope of the relationship?

Answer 1

slope = 4

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 2, - 13) and (x₂, y₂ ) = (2, 3) ← 2 ordered pairs from the table

m =
`(3-(-13))/(2-(-2))` =
`(3+13)/(2+2)` =
`(16)/(4)` = 4
