Let's break down the calculations step by step.
Part A
-
Calculate the rise from (3, 30) to (12, 120):
- Rise = \( y_2 - y_1 = 120 - 30 \)
- Rise = \( 90 \)
-
Calculate the run from (3, 30) to (12, 120):
- Run = \( x_2 - x_1 = 12 - 3 \)
- Run = \( 9 \)
-
Calculate the slope:
- Slope = \( \frac{\text{rise}}{\text{run}} = \frac{90}{9} \)
- Slope = \( 10 \)
Part B
-
Calculate the rise from (0, 0) to (6, 60):
- Rise = \( y_2 - y_1 = 60 - 0 \)
- Rise = \( 60 \)
-
Calculate the run from (0, 0) to (6, 60):
- Run = \( x_2 - x_1 = 6 - 0 \)
- Run = \( 6 \)
-
Calculate the slope:
- Slope = \( \frac{\text{rise}}{\text{run}} = \frac{60}{6} \)
- Slope = \( 10 \)
Part C
- The slope from (0, 0) to (6, 60) is equal to the slope from (3, 30) to (12, 120).
