find the rate of change of the linear function from the point (0,12) to the point(20,8).

Question

rate of change of the linear function from the point (0.12) and to the point(20,8)

Answer 1

So we need to look at the rise over run with slope formula, (y₂ - y₁) / (x₂ - x₁):

^{8 - 12} / _{20 - 0}

-⁴/₂₀

Simplify the fraction to get the final answer.
