Thank you for the opportunity to help you with your question!

Rearrange the equation x = 3y - 9  into the form y = mx + b

3y = x + 9

Divide by 3:

y = 1/3x + 3

since we were able to put the equation in the y = mx + b form it IS a linear function.

Please let me know if you need any clarification. I'm always happy to answer your questions.
