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 :)

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