usage the table to uncover the price of change. Climate graph it.

Time     driving     ( h )   x street     took trip   ( mi )   y 2 80 4 160 6 240

A rate of change is a rate that defines how one quantity transforms in relation to another quantity.

rate     the     adjust = readjust     in     y change     in     x = adjust     in     distance readjust     in     time = 160 − 80 4 − 2 = 80 2 = 40 1

The rate of readjust is 40 1 or 40 .
