Question

pizza general charges 10 dollars per medium pizza. find the slope, or the change in vertical distance for a given change in horizontal distance. in other words, by how much does the total cost increase every time you buy 1 more pizza? slope = \frac{vertical distance}{horizontal distance}

Explanation:

Step1: Identify two points

Use points $(1, 10)$ and $(2, 20)$ from the graph.

Step2: Calculate vertical/horizontal change

Vertical change: $20 - 10 = 10$; Horizontal change: $2 - 1 = 1$

Step3: Compute slope via formula

Slope = $\frac{\text{vertical distance}}{\text{horizontal distance}} = \frac{10}{1}$

Answer:

10
