Question 43797: Help please: Determine algebraically whether the lines are parallel, perpendicular or neither. State the number of solution.
x - y = 5
x = 5 - y Answer by Nate(3500) (Show Source):
You can put this solution on YOUR website! x - y = 5
-y = -x + 5
y = x - 5
and
x = 5 - y
x - 5 = -y
-x + 5 = y
The slopes are perpendicular, so the lines are perpendicular. There is only one solution.
