Answer:
a. 66c per oz of cheese bought
b. 66x
Explanation:
a. Looking at the graph you can see that the price of 1 oz of cheese is 66 cents. As the graph is a straight line it is seen that the price rises by 66 cents per oz bought.
b. We use the answer of 66 cents per oz of cheese and change the cents out for x, to be able to a y = mx + b equation and since it starts at 0 the b = 0.
