Answer:

3y = 9x

Y= 3x

-3x+y = 8

Y= 3x +8

Explanation:

Y= 3x+5

To determine the Line parallel to the above line equation, we have to recall the principle of parallel line .

From principal of parallel line.

M= m'

Means the gradient of the both equation will be equal.

From the above equation.

The gradient= 3

The gradient is the coefficient of x

Comparing to the options giving

Let's look for the options with the coefficient of x = 3

3y = 9x

Y= 3x........ number 1

-3x+y = 8

Y= 3x+8 ... number 2

Other equation will not give is a coefficient of 3
