Answer
Interpretation of slope: For every one-inch increase in a child’s height, it is expected that his/her head circumference will increase by 0.1827 inches.
Interpretation of intercept: No child can be 0 inches tall. As such, it would be unreasonable to try to use this equation to predict values where x = 0. Thus, the y-intercept has no meaning.
