Question

The first hill of the Texas Giant at Six Flags over Texas drops 137 feet vertically over a horizontal distance of about 103 feet. The Magnum XL-200 at Cedar Point in Ohio drops 195 feet vertically over a horizontal distance of about 113 feet. Which coaster has the steeper slope?

Answer 1

The Texas Giant's coordinates are (103,137) while the Magnum XL-200's are (113,195). Now just use the slope formula to find the slope, using (0,0) as the second point in each calculation.
(y1-y2) / (x1-x2)
137-0 / 103-0
137/103
1.33
and
195-0 / 113-0
195/113
1.73
So the Magnum XL-200 has the steeper slope.
