To find the slope of the line determined by the points (2, 24) and (4, 48), we can follow these steps:
-
Determine the rise (change in y-coordinates):
- The rise is: \( 48 - 24 = 24 \).
-
Determine the run (change in x-coordinates):
- The run is: \( 4 - 2 = 2 \).
-
Calculate the slope (rate of change):
- The slope (m) is given by the formula: \[ m = \frac{\text{rise}}{\text{run}} = \frac{24}{2} = 12 \].
Putting it all together, we have:
- The rise is the change in the y-coordinates: \( 48 - 24 \), which is equal to 24.
- The run is the change in the x-coordinates: \( 4 - 2 \), which is equal to 2.
- The rate of change (slope) is 12 pounds per month.
