A rate of readjust is a rate that defines how one quantity alters in relation to another quantity. If x is the live independence variable and also y is the dependency variable, climate

price     of     change = change     in     y change     in     x

rates of adjust can be positive or negative. This corresponds to boost or decrease in the y -value between the two data points. When a amount does not readjust over time, it is referred to as zero price of change.

### hopeful rate of change

once the worth of x increases, the value of y increases and also the graph slants upward. ### an unfavorable rate of adjust

once the worth of x increases, the value of y decreases and the graph slants downward. when the value of x increases, the value of y remains constant. The is, there is no change in y value and the graph is a horizontal heat . You are watching: Constant rate of change on a graph

Example:

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

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

A rate of adjust is a price that explains how one quantity alters in relation to an additional quantity.

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

The price of adjust is 40 1 or 40 .
