Question

I need help on this please

Answer 1

y = 13.5 when x = 3.

Explanation:

First, we find the equation of the proportional relation.

The standard form an equation of direct variation is

y = kx

We need to find the number for k for this relation.

We use the given point.

y = 9 when x = 3.

9 = k × 3

k = 9/2

k = 4.5

The relation is:

y = 4.5x

Now we let x = 3

y = 4.5(3)

y = 13.5

Answer 2

Answer: 13.5

Step-by-step explanation: Trust me Ik or you can say 13 1/2 when x equals 3
