table. Which statement
about the relation is true?
A. It is a direct variation because y = -2.5x + 12.5
B. It is an inverse variation because y = -2.5x + 12.5
C. It is a direct variation because 10 = xy
D. It is an inverse variation because 10 = xy

Direct and Inverse Variation 300
An experiment is conducted on a container of gas
that is kept at a constant temperature.
~ When the pressure on the gas is 30 pounds
per square inch, the volume is 120 cubic
inches.
~When the pressure on the gas is 40 pounds per
square inch, the volume is 90 cubic inches.
Do the volume and pressure vary
directly or indirectly? Why?
Template by Modified byBill Arcuri, WCSD Chad Vance, CCISD
AnswerThe volume of the gas
varies inversely with the pressure because
vp = 3,600..
