Question

5. Determine whether the following two lines are parallel, perpendicular, neither, or both.
L1: passes through (6, 4) and (3, 6)
L2: passes through (5, 4) and (3, 1)

both parallel and perpendicular

perpendicular

parallel

neither parallel or perpendicular

Answer 1

two parallel lines must have the same coefficient
k1=(y2-y1)/(x2-x1)=(6-4)/(3-6)=-2/3
k2=(1-4)/(3-5)=3/2
so the lines aren't parallel
2 lines are perpendicular when K1*k2=-1---> -2/3*3/2=-1
so the lines are perpendicular :)

Answer 2

(I'm not sure with wht you express the coefficient..but in Albania we use K that's why I used it :)

Answer 3

oh you're an albanian ?

Answer 4

the coefficient told by angela is also called the slope of the line...

Answer 5

Yea :) Have you heard abt it?
