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 representation that is not proportional.

A. A graph showing a straight line through the origin
B. A table with \(x\text{-}\text{values}\) \(2,~5,~8\) and \(y\text{-}\text{values}\) \(6,~15,~24\)
C. The equation \(y~=~3x\)
D. A streaming service costs \(\$8~\text{per}~\text{month}\) plus \(\$2~\text{for}~\text{each}~\text{movie}~\text{rented}\)

Four option cards. Option A is a straight line graph through the origin. Option B is a table with x-values 2, 5, 8 and y-values 6, 15, 24. Option C is the equation y = 3x. Option D is a streaming service context with $8 per month plus $2 for each movie rented. Open full size
