Aramp slopes from a warehouse door down to the street. the height of the ramp is 5 feet, and the ramp ends 10 feet from the base of the warehouse. what is the slope of the ramp?
a
1/2
b
1/3
c
2/1
d
3/4

If you graph this, your first point will be at (0,5), as the ramp is at the warehouse door but 5 feet up. The second point is (10,0) as it is touching the ground but it's 10 feet away from the warehouse.
To find slope, you do (y2-y1)/(x2-x1).
When substituting in the variables, you get (0-5)/(10-0), which is -5/10, which is simplified to -1/2. Of course, that is when the warehouse is Quadrant II. If you look at it from another point of view, the slope will be positive so your answer is A) 1/2.
If this was unclear feel free to comment :)
