Does the following graph represent a proportional or non-proportional relationship? Explain your reasoning.

Answer:
Non-proportional relationship
Step-by-step explanation:
Proportional relationships must pass through the origin. Otherwise, at [tex]x=0[/tex], we lose the constant of proportionality, and the y-value at [tex]x=0[/tex] becomes correlated only to the y-intercept.
The format for a proportional relationships is given by [tex]y=kx[/tex], where [tex]k[/tex] is some constant referred to as the constant of proportionality.
