How do you determine the constant rate of change from a table of x and y values.

A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x
x
is the independent variable and y
y
is the dependent variable, then

Rates of change can be positive or negative. This corresponds to an increase or decrease in the y
y
-value between the two data points. When a quantity does not change over time, it is called zero rate of change.

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
