Which cheese is less expensive per ounce, 16 ounces of Colby Jack cheese for $7.75 or 24 ounces of American cheese for $10.25?

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.

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

yes, whats the problem?
