A ratio of two quantities measured in different units
Rate
A rate that has a denominator of one when expressed in fraction form
Unit rate
An equation that states two ratios are equal
Proportion?
When the ratios Y/X for X doesn’t equal 0 all equal nonzero constant k
Direct variation
When the products xy all equal a nonzero constant k
Inverse variation
And direct and inverse variation the constant K is called the ____________
