the number of pennies on the x-axis and the distance
from the fulcrum on the y-axis. Then draw a smooth

Inverse Variation: A
relationship between two
variables where x and y can be

written in the form  = where

k is a constant not equal to 0.
Example 1
Given y varies
inversely as x, and
y=3 when x=8. Write
and graph the inverse
variation function.
Example 2
The time it takes (t) for ASB to hang
posters around the school varies
inversely as the number of ASB
students, s. If 20 students can hang
a set of posters in 62.5 minutes,
how many students would be
needed to hang the set of posters in
25 minutes?
