A pediatrician records the age (in months) and height (in inches) of a baby over time and creates a scatter plot. Using this scatter plot, the pediatrician determines that the model that can be used to predict the baby's height is y=1.3x+18, where y is the height of the baby and x and the age of the baby. What does the slope of the equation tell us?

A
The baby grows 1.3 inches per month.

B
The baby was 1.3 inches when born.

C
The baby grows 18 inches per year.

D
The baby was 18 inches when born.
