Question

19.   Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

y = -7/8x - 1
32x - 28y = -36

A. parallel
B. perpendicular
C. neither

anonymous · Answer

get both equations into slope intercept form y=mx+b
I'd simplify the second equation before doing anything else to it.
You can divide both sides of it by 4 to get
8x - 7y = -9

anonymous · Answer

parallel line the slopes will be the same
perpendicular they will be negative reciprocals of each other.
