Answer the following questions:

1.	Examine the ratios you recorded in Step 2.  How do they change as the ramp becomes steeper?

2.	Examine the ratios you recorded in Step 3.  What happens to the ratio when the run stays the same and the rise increases?

3.	Suppose you want to construct a skateboard ramp that is not as steep as a ramp with a rise/run of 18/24 inches.  List three different sets of rise/run measurements that will result in a less steep ramp.  Verify your predictions by calculating the ratio rise/run of each ramp.

4.	Draw a line on a coordinate graph that goes through (1,2) and (2,4).  Now draw a line through the origin with a rise/run ratio greater that the original line.  Then draw a line through the origin with a ratio less than the original line.  Explain your reasoning using the words rise and run.
