Topics for December 10th

Today We Discussed:

Direct variation was the topic of today's class.  Direct variation is simply a function that can be expressed by the formula

y = kx 

where k is the constant of variation
and k ≠ 0. 

We looked at this relationship from many different perspectives: we determined if an equation represents a direct variation relationship, we derived direct variation equations, and we used the direct variation formula to solve problems.

Vocabulary: direct variation, constant of variation
