What is the rate of change between (6,12) and (8,20)

Irina-Kira [14]

Step-by-step explanation:

It might be easier thinking of "rate of change" as the slope. Since you'll be finding a slope, then, use the formula $m=\frac{y_2-y_1}{x_2-x_1}$ and substitute the values.

$m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{20-12}{8-6}\\m=\frac{8}{2} \\m=4$

Answer:

$m=\frac{4}{1}$ or $m=4$
