C

Step-by-step explanation:

We are trying to find the profit for every pizza sold. Since looking at the x axis, the point in which its x coordinate is 1 cannot be easily identified. Thus, we shall derive the answer using a point that can be easily identified.

We observe that the two points, (10,12) and (20,24) sits nicely on the graph. I will be using the first coordinate above to derive the answer.

For every 10 pizzas sold, $12 of profit is made.

10 pizzas $12 profit

1 pizza $12 ÷10= $1.20

Hence, the unit rate of profit for the pizzas is $1.20 per pizza.
