The constant of proportionality is 2.5. The equation that represents this proportional relationship is y=2.5x.

Step-by-step explanation:

to find the constant of proportionality -> for every time x goes up, what does y go up by? when x goes up by 2, y goes up by 5. difference of y/difference of x = 5/2 =2.5.

to find the equation -> y=?x. plug in the constant of proportionality in the question mark. so, y=2.5x.
