Question 173186
re write these in y=mx+b forms......parallel have equal slopes and perpendicular have negative inverses
:
8y=3x+18--->y=(3/8)x+9/4....so a slope of 3/8
:
12y=-32x-18---->y=-8/3x-3/2...so a slope of -8/3
:
when negative inverses are multiplied they equal -1
:
3/8(-8/3)=-1.
:
therefore the two lines are perpendicular
