Mariana is making a large pot of pasta. She mixes together 5 1/8 pounds of pasta, 6 pounds of sauce, and 4 7/8 pounds of onions. To find out how many 12 pound servings can she make, which two equations would you need?

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
