    If the lines are parallel, their slopes will be identical. If the lines are perpendicular, the product of their slopes will be -1. Rearrange each equation into slope-intercept form: \(y=mx+b\) where \(m\) is the slope. You can compare the slopes after doing that.

    What are the slopes you got for the lines x-2y=7 and 2x+y=9?
