Can you identify a pattern of change between each row in the table?

Practice makes perfect
To determine the rate of change in the given table, let's see if we can identify a pattern of change between each row. Note that "time" is the independent variable, usually represented by x, and "height" is the dependent variable, usually expressed by y.
Rate of change is defined as the change in dependent variable over the change in independent variable.
rate of change=Change in y/Change in x
Looking at the patterns of change in the table, we see that every time x increases by 3, y increases by 20. We can substitute these values into the equation to obtain the rate of change.
