Question

pizza general charges 10 dollars per medium pizza. fill in the vertical distance from (1, 10) to (2, 20) on the graph. in other words, if you buy 1 more pizza, by how much does the total cost change? slope = \frac{vertical\\ distance}{horizontal\\ distance}

Explanation:

Step1: Identify y-values of points

The points are $(1, 10)$ and $(2, 20)$, so $y_1=10$, $y_2=20$.

Step2: Calculate vertical distance

Subtract the smaller y-value from the larger one.
$\text{Vertical Distance} = y_2 - y_1 = 20 - 10$

Answer:

10
