Question

a mountain drops 90 ft over a horizontal distance of 875 ft.. what is the slope of the mountain?????

Answer 1

slope = rise over run
rise is height which is y coord
run is length which is x coord

slope = y / x

where y is the height which is 90ft
and x is the length which is 875ft

Answer 2

to add, when you divide by x you are saying, per x what is the amount of y? which is exactly what the slope is
