Question

What is the slope of the function, represented by the table of values below?

Answer 1

B

Explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 2, 10) and (x₂, y₂ ) = (8, - 10) ← 2 ordered pairs from the table

m =
`(-10-10)/(8-(-2))` =
`(-20)/(8+2)` =
`(-20)/(10)` = - 2 → B
