If our options to answer this from are: • y=2x+1 • y+4x=8 • y=5x Then to find a proportional relationship represented by an equation, we look for an option where its y=#x, so we can REMOVE option B. And so your answer is C. as y=5x is a proportional relationship between x and y since its not adding or subtracting a number from either y or x.
