Question

What is the rate of change of this table?

Answer 1

- 6

Explanation:

The rate of change of the values is the slope m

Calculate m using the slope formula

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

with (x₁, y₁ ) = (- 2, 32) and (x₂, y₂ ) = (0, 20) ← 2 ordered pairs from the table

m =
`(20-32)/(0+2)` =
`(-12)/(2)` = - 6 ← rate of change
