Answer

Explanation:

Step1: Select two points

Let's take two points on the graph: (1, 10) and (2, 12.5).

Step2: Calculate the slope

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 1,y_1 = 10,x_2 = 2,y_2 = 12.5$. So $m=\frac{12.5 - 10}{2 - 1}=\frac{2.5}{1}=2.5$. The slope represents the increase in cost per additional slice of pizza.

Answer:

$2.50
