To determine the rate of change (slope) for both graphs, we use the formula:

\[
\text{Rate of Change} = \frac{\text{Change in } y}{\text{Change in } x}
\]

### Graph A
Points: (1, 220) and (3, 160)

\[
\text{Rate of Change} = \frac{160 - 220}{3 - 1} = \frac{-60}{2} = -30
\]

**Rate of change for Graph A: -30 feet per second.**

### Graph B
Points: (4, 10) and (8, 20)

\[
\text{Rate of Change} = \frac{20 - 10}{8 - 4} = \frac{10}{4} = 2.5
\]

**Rate of change for Graph B: 2.5 cups per loaf.**

Let me know if you'd like further clarification!

### Questions:
1. What does a negative rate of change indicate in Graph A?
2. How can you interpret the rate of change for Graph B in real-world terms?
3. Could you determine the equations for each line?
4. What happens to the graphs if the rate of change increases or decreases?
