Mike’s friends ask him to make his popular ten-layer dip for the tailgate party at the big football game. The ten layers are: three layers of mashed avocado, two layers of cheddar cheese, and one layer each of refried beans, sour cream, sliced olives, chopped tomatoes, and green onions. How many ways can Mike make the ten layers in a glass serving pan?

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.
