the cost of frozen yogurt by per ounce.

Explanation:

Step1: Identify two points on the line

Let's take two points $(x_1,y_1)=(2,2)$ and $(x_2,y_2)=(10,6)$.

Step2: Use the slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Substitute the values: $m=\frac{6 - 2}{10 - 2}=\frac{4}{8}=\frac{1}{2}$.

Answer:

increases; $\$0.50$
