At Knowre Cafe, Maureen sells $105$ coffee drinks and $25$ hot cocoas every day. How many coffee drinks and hot cocoas will Maureen sell in $3$ weeks?

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.
