Do you know the formula for the average rate of change? @Avenged7x

anonymous · Answer

i think it's $$A(x) \frac{ f(x)-f(y) }{x-y  }$$

igreen · Answer

No.

This is it:

$m = \dfrac{y_2-y_1}{x_2-x_1}$

igreen · Answer

Sorry my mistake:

y1=0
y2=-5

x1=-4
x2=4

igreen · Answer

Plug it into the formula:

$m = \dfrac{y_2-y_1}{x_2-x_1}$

$m = \dfrac{-5-0}{4+4}$

Simplify:

$m = \dfrac{-5}{8}$

Divide:

$m = -0.625$

Well the answer is B..

igreen · Answer

-5/8 = -0.625
