<u>Answer:</u>
<u>Step-by-step explanation:</u>
We know that y varies directly with: ∝ .
To convert this proportionality into an equality, we need a constant .
=
We know that when so we can write it as:
Now that we know the value of the constant is equal to , we can write the this relation as:
as y varies directly with x, the following equation can be established.
y = a * x
from the condition given by the question, we can know that
7.5 = a * 3
a = 7.5 / 3 = 2.5
thus, we can infer that the equation is
y = 2.5 * x
