Too Big, or Not Too Big
Enter the equation of one of the Pet Sitter constraints in the form of ac + bd = t, where c represents the number of cats, d represents the number of dogs, and t represents the total space, total cost, or total time. Pick a specific number of cats and dogs and decide if that number of cats and dogs would be "too big," "not too big," or "just right" for the constraint. Enter the coordinates of the point in the appropriate boxes and press the button corresponding with your prediction to plot the point. If your prediction was correct, the point will be plotted in the correct color: green, orange, or red. If not, the point will be plotted in black. Try to avoid getting black points while you are trying to plot at least five points of each of the other colors.
