**Match the Regression Equation with the Appropriate Graph**
(Note that the x- and y-axes are broken.)
Equation: \( y = -1.1x + 52.3 \)
**Options:**
**A)**
- **Graph Description:** This graph plots Btu/hr against Cooling Capacity (in BTU).
- **Graph Features:** The graph shows a positive linear trend.
**B)**
- **Graph Description:** This graph plots Extra Time (hours per week) against Work Time (hours per week).
- **Graph Features:** The graph shows a negative linear trend.
**C)**
- **Graph Description:** This graph plots Fiber (in grams) against Protein (in grams).
- **Graph Features:** The graph shows a negative linear trend.
**D)**
- **Graph Description:** This graph plots Income (dollars per month) against Age (in years).
- **Graph Features:** The graph shows a positive linear trend.
**Explanation:**
To match the regression equation \( y = -1.1x + 52.3 \), look for a graph displaying a negative slope. Both Graphs B and C show negative trends. However, the context or values of the axes might help differentiate further.
