Tables are Proportional When...

• The ratios of the numbers in the table are equivalent, the relationship is proportional. 

  
  

You know equations are poroportional when...

• The y-intercept is 0. This means that it is on the origin!

You know a graph is proportional when...

• It is linear

• Line intersects the origin (0,0)

When a linear relationship is proportional...

• We can also say that x and y have direct variation.

• If an equation is proportional, we can say that is a direct variation equation
