Given the equations of lines as Line L1 y=x-4, Line L2: y=4x-1, Line L3: y=sx-9, Line L4: y=-3x-10, Line L5: y=dx-10 Find p, s, and d such that L1 and L2are parallel, L3 and L4 are perpendicular, and L1 and L5 are parallel.

Question

anonymous · Answer

L1 an L2 are parallel? I think they're not, since they don't have the same slope...except you made a mistake in copying down the question

anonymous · Answer

My guess is it's supposed to be y=px-4 since the question asks about a p and there isn't  one anywhere.

anonymous · Answer

L3 perpendicular to L4 when they have negative reciprocal slope to each other
L4 has slope m=-3...therefore slope s in L3 = 1/3

Yes...we need to solve for the first part to keep going for the last one :D
