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.
