Hi
line y=5/6x-4 m = 5/6
line that is perpendicular to this lineand passes through (5,6)
***Using point-slope form,
y - 6 = (-6/5)(x-5)
y-6 = (-6/5)x + 6
y = (-6/5)x + 12 Green Line
line that is parallel to this lineand passes through (5,6)
y - 6 = (5/6)(x-5)
y = (5/6)x-25/6 + 36/6
y = (5/6)x + 11/6 Blue Line
