Each week for the last 9 weeks, Sandra deposited $5 into her piggy bank, which already had $15 in it. Now she has saved enough money to buy tickets for all 5 of the members of her family to go see a movie. Which expression and value show the cost of each movie ticket? [9 × 5 + 15] ÷ 5; $9 [9 × 5 + 15] ÷ 5; $12 9 × 5 + 15 ÷ 5; $9 9 × 5 + 15 ÷ 5; $12

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.
