Why do equivalent ratios form a straight line when graphed? The vertical distance between points is constant, and the horizontal distance between points increases with each point.

The ratio of the change in y-values to the change in x-values is equivalent for any two points in a graph of equivalent ratios.

The horizontal distance between points is constant, and the vertical distance between points increases with each point.

The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

D-The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

Step-by-step explanation:

i just did the quiz

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.
