The initial value is 22, and the rate of change is 15.
The initial value is 32, and the rate of change is 1.
The initial value is 32, and the rate of change is 15.

Answer 1

Tim will age one year for each year of marriage, so the slope (rate of change) is 1. The first point plotted is (22, 54) indicating Tim was 54 after 22 years of marriage. Thus he must have been 54 - 22 = 32 years old after 0 years of marriage.

The intial value is 32, and the rate of change is 1.
