Both are in slope-intercept form so that you can determine the slope of each by inspection. If the slopes are equal, the graphs are parallel (or possibly coincident). If the slopes are negative reciprocals, then the graphs are perpendicular. Otherwise, neither.

Not parallel nor perpendicular. They intersect at x=4/11 and y=61/11
