Question

wheelchair ramps for access to public buildings are allowed a maximum of one inch of vertical increase for every one foot of horizontal distance. Would a ramp that is 10 feet long and 8 inches tall meet this guideline? Explain your reasoning

Answer 1

If you image that the starting point of the ramp is on a coordinate plane being the point (0,0) and the top of the ramp being at (120,8) you can use the slope of the line intersecting the two points to see if the slope is ≥ 1

Answer 2

yes
if x represents how long it is, y represents how tall it is
then x≥y according to the given information.
since x=10, y=8 in this situation
it meets the guideline
