Direct and Inverse Variation Continued… Tuesday, September 2, 2014
Where might I find this in the real world?
What is the proportion for Direct Variation?
What is the proportion for Inverse Variation?
Remember the Direct and Inverse Variation equations? How can we use the equations to find the constant of variation (k)?
Examples: 1. y varies directly as x, and y = 4 when x = y varies inversly as x, and y = 2 when x = 6.
You try 1. If y varies directly as x, and y = -3 when x = If y varies inversely as x, and y = -1 when x = 2.
Can we solve word problems that have both types of variation? Let’s try it!
