Which equation represents a proportional relationship? a) y = 9x b) y = 9x + 1 c) y = 9x + 9 d) y = 9 x

A) y = 9x

Step-by-step explanation:

Proportional relationships shows the relationship between two or more variables where their ratios are equivalent in a given expression. It is majorly a direct relation, which implies that as the value of on variable increases, the value of the other variable also increase.

From the expressions given, the first shows a good proportion between the variables given.

So, y = 9x is the answer.
