The graph shows the relationship between the number of hours Quan works and the number of dollars he earns. Which statement is not true?
A. The equation h=15d models the relationship
B. The dependent variable is d.
C. The equation d=15h models the relationship.
D. The independent variable is h.
A because for example, when x (Time in hours) is 5, y (Dollars) is 75. So if you substitute h=15d you get 5=15•75 and 15•75 is clearly not 5, so it is wrong.
