Rachael is a nurse. she earns 12 vacation days after working 768 hours. how many hours does rachael need to work to earn 1 vacation day? remember to include units! (example: 12 hours) question 4 options: spell check

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.
