You can put this solution on YOUR website! Determine whether the lines are parallel, perpendicular, or neither.
-8-5x=8y
-8x+5y=5
**
Rewrite given equations in standard form for straight lines: y=mx+b, m=slope, b=y-intercept
-8-5x=8y
8y=-5x-8
y=-5x/8-1
slope=-5/8
..
-8x+5y=5
5y=8x+5
y=8x/5+1
slope=8/5
..
Slopes are negative reciprocals of each other, therefore, lines are perpendicular
