Li believes that the graph shows a direct variation. On a coordinate plane, a line goes through points (0, 1) and (2, 0). Why is
Li incorrect in saying that the graph shows a direct variation? The graph does not have a constant rate of change. When the x-value is 0, the y-value is 1. The slope is negative. The relationship is proportional.
mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other. 2 : an equation or function expressing direct variation — compare inverse variation.
I don't tell straight out answers but I hope this helps!
