Arectangular plot of ground is to be enclosed by a fence and then divided down the middle by another fence. if the fence down the middle costs $3 per running foot and the other fence costs $4 per running foot, then find the relationship between x and y with $880.00 worth of fence:

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.
