Answer:

y = -3x + 8.3

Explanation:

You need to rearrange 9x + 3y = 22 in the form y = mx +c.

9x+3y = 22

3y = -9x +22

y = -3x + 7.3

As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.
