Answer:

Yes.

Explanation:

Yes this is a linear equation.

First we need to simplify the equation down. We can do this by working through all the indicated subtractions shown in this equation.

3x - 2x - 9x = -8x

f(x) = -8x + 9

This is a linear equation. Check your work on a graphing calculator.
