As indicated in the scatterplot of Son's height vs Fathers height, the x-intercept is 64
inches.

The x-intercept has no meaning because a father cannot be 0 inches tall. The slope means that for every inch in the father height the son's height
(increases, decreases) by
inches.

How many sons in the study are the same height as their father?

How many sons in the study are shorter than their father?

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

the answer is a.
