Question 1122252: Decide whether Line 1 and Line 2 are parallel, perpendicular or neither . Line 1 passes through (3,-3) and (5,3). Line 2 passes through (3,6) and (9,4). Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Check their slopes:
Line 1 has a slope of change in y/change in x and is 6/2 or 3
Line 2 has a slope of -2/6 or -1/3
3 and -1/3 are negative reciprocals of each other. The lines are perpendicular to one another.
