Direct and Inverse Variations

After reviewing the story and picture problems from the weekend homework, we talked a little about direct variation (form is y = kx or y = kx +b) and compared this to inverse variations (form is xy = k). In direct variations, the function looks like a line when graphed on the coordinate grid. This is not true when inverse functions are graphed. The resulting graph of these problems gives you a curve (or two), with limitations put on each of the variables.
