please help!
The following equation can be used to predict the average height of boys anywhere between birth and 15
years old: y = 2.79x +25.64 where x is the age (in years) and y is the height (in inches).
a. What does the slope represent in this problem? Interpret it in context.
b. What does the yintercept represent in this problem? Interpret it in context.

slope is the boys' growth rate, inches/year
the yintercept is where x=0, that is, the height at birth. Wow! 25.64 inches at birth! Probably just a fudge factor so that height in subsequent years is a decent approximation.
