You can
put this solution on YOUR website!locate the x variable and y variable in the following:
a.pressure and volume
pressure
----------------
b.force and weight
weight
----------------
c.distance and time
time
-----------------
Comment: Actually, either of the two named effects
could be the "x" variable. Sometimes you want to
solve for one; at other times you need to solve for
the other.
