DirectVariation

EQUIVALENT PROPORTIONS IS DIRECT VARIATION!!! !
2/12 is the same as 4 to 24 is the same as 6 to 36….etc. So, this varies proportionally!

NOT A DIRECT VARIATION
1/6 is not the same as 2/8 or 3/10 or ……….

A direct-variation equation is always linear and always contains the point (0, 0).
The variables x and y either increase together or decrease together.

SITUATIONS THAT CHANGE PROPORTIONALLY
Ms. Evans Example: Movie tickets and the total amount of money it’s going to cost
Zero Tickets=Zero dollars
The more movie tickets I buy, the more total money I will have to pay!
