@ganeshie8 ????

ganeshie8 · Answer

"average rate of change" is same as "slope"

ganeshie8 · Answer

(15, 4)   and  `(25, -16)

find the slope

anonymous · Answer

WAIT

anonymous · Answer

-24?

ganeshie8 · Answer

Easy, slope is given by
$$\dfrac{-16-4}{25-15} = \dfrac{-20}{10} = -2$$

anonymous · Answer

SO, THAT the answer? -2?
