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} = \boxed{?}

Explanation:

Step1: Identify two points

We can use the points \((1, 10)\) and \((2, 20)\) from the graph.

Step2: Calculate vertical and horizontal distance

Vertical distance (change in \(y\)): \(20 - 10 = 10\)
Horizontal distance (change in \(x\)): \(2 - 1 = 1\)

Step3: Compute slope

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

Answer:

\(10\)
