Amachine makes 300 boxes in 15 minutes. which expression equals the unit rate in boxes per hour

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.

because that’s us why

d is ur answer hopes this i dont really know how to explain it to u.

sorry but i cant draw that
