we need more info to solve this

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

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.

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
