Determine whether a relationship is proportional from a table, graph, equation, or context.

Classify mixed representations for proportionality

Problem

Evaluate each representation for proportionality. Report the letter of the representation that is not proportional.

A. A recipe uses \(3~\text{cups}~\text{of}~\text{flour}~\text{for}~\text{every}~2~\text{batches}\)
B. The equation \(y~=~1.5x\)
C. A table with \(x\text{-}\text{values}~1,~3,~5\) and \(y\text{-}\text{values}~4,~12,~21\)
D. A graph of a straight line that goes through the origin

Four option cards. Option A is a recipe context showing 3 cups of flour for every 2 batches. Option B is the equation y = 1.5x. Option C is a table with x-values 1, 3, 5 and y-values 4, 12, 21. Option D is a straight line graph through the origin. Open full size
