The table shows the number of cups of caramel required for different amounts of flour in a caramel cookie recipe. The ratio of cups of caramel to cups of flour is constant. Let c = cups of caramel needed when using 20 cups of flour Which proportion can be used to determine the value of c? A. B. C. D.

look a the sides they are perpendicular

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.
