Select the equations that show a proportional relationship between and .

Both equations and exhibit a proportional relationship between and . In these equations, the constant coefficients (7 and 10) represent the constant of proportionality, meaning for every unit increase in , increases by 7 and 10 units respectively. This linear relationship implies that the ratio remains constant, confirming their proportional nature!

To clarify, a proportional relationship can be identified by the presence of a straight line passing through the origin when graphed on a coordinate plane. So, if you were to plot these equations, you’d find perfectly straight lines starting right from the point (0,0) – a hallmark of proportionality!
