This storyboard does not have a description.
Mrs. Goozh has a strict card policy. Every time that you get 2 cards, you get one less page of homework.
This means that the constant of proportionality is -1/2 page of homework per card, or -1/2 over 1. It also means that the rate of change is -1/2 minutes of lunch per card.
The amount of homework pages depends on the amount of cards a student receives. As the amount of cards increases, the amount of homework pages decreases.
The slope in this situation is -1/2, while the y-intercept is 0. The slope represents the pages of homework reduced.
Since this situation has no y-intercept, this situation on a graph would run through (0,0). If this situation were to be graphed, the equation would be y=(-1/2)x.
The amount of homework pages reduced is the dependent variable(y) and the amount of cards is the independent variable(x).
