Step-by-step explanation:

This is not a linear equation!! You have to have 2 variables, y and x in the same equation in order for this to be made into a line.

You can use the equations y=kx for proportional lines or y=mx+b, which is slope-intercept form.

For example, y=2x-4.

Sorry I can't do more.
