Question

What is the rate of change of y with respect to x got this function

Answer 1

B

Explanation:

The rate of change of a linear function is the slope m

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 12) and (x₂, y₂ ) = (0, 3) ← 2 points on the table

m =
`(3-12)/(0+2)` =
`(-9)/(2)` = -
`(9)/(2)`
