Algebra homework help. Finding the Slope.?

Question

(Please show/explain how to set this word problem up, then how to go about solving.)

The upper deck at Comiskey Park in Chicago has produced, among other complaints, displeasures with its steapness. It is 160 ft from home plate to the front of the upper deck and 250ft from home plate to the back. The top of the upper deck is 63 ft above the bottom. What is its slope? (consider the slope as a positive number here.)

Answer 1

Slope = rise / run
rise = 63 ft.
Run = 250 from home plate to back - 160 from home plate to front

slope = 63 / (250 - 160) = 63 / 90 = 7/10 = .7 (solution!)
