and many more that will give you the CORRECT answer and will give u a step by step explanation on how it was answered

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.

maya’s expression will generate the wrong sum because she violated the commutative property.
