Find the slope of each line. If the slopes are the same, the lines are parallel. If the slopes are negative reciprocals, the lines are perpendicular.
.
L1 with equation x � 6y = 30
m = -(A/B) [Formula for the slope of a line in standard form]
m =-(1/-6) = 1/6[Plug-in the values]
m = 1/6
.
L2 with equation 6x + y = 6
m = -(A/B) [Formula for the slope of a line in standard form]
m = -(6/1) = -6 [Plug-in the values]
m = -6
.
The slopes are negative reciprocals, therefore L1 and L2 are perpendicular.
