One rollercoaster starts 72 feet above the ground and descends to ground level over a 24-foot horizontal distance. A second rollercoaster starts 39 feet above the ground and descends to ground level over a 13-foot horizontal distance. Are the descending parts of these rollercoasters parallel?
A.
Yes; when descending, the rollercoasters have the same slope.
B.
No; the first rollercoaster has a greater slope than the second rollercoaster.
C.
No; multiplying the slopes of the two rollercoasters does not give a product of –1.
D.
The two roller coasters do not have the same horizontal change, so they cannot be compared.
