An electrician charges$40 to come too your house. so also charges $55 for each hour she works. the electrician charges you a total of $190. how many hours does the electrician work at you house? use h for the number of hours.

the correct option is b

step-by-step explanation:

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.
