Question 684110: tell without graphing is this parallel, perpendicular or nethier parallel or pendendicular.
5x - 6 y = 19
6x + 5y = -30

Answer by ReadingBoosters(3246)   (Show Source): You can put this solution on YOUR website!
Put into slope intercept format
5x - 6y = 19
-6y = 19 - 5x
y = 5/6x - 19/6
...
6x + 5y = -30
5y = -30 - 6x
y = -6/5x - 6
...
With slopes of and , which are negative reciprocals,
the lines are .
