Lines k and m are parallel to each other. Is the slope of line k positive?
(1) Line k passes through the point (3, 2).
(2) Line m passes through the point (-3, 2).
consider equation of line k :
2=3s+c=>s=(2-c) /3 => s can be +ve or -ve insufficient
2=-3s+d=>s=(d-2) /3 => s can be +ve or -ve insufficient
consider both (1) and (2)
c+d =4 -> I
s= (d-c)/6 => (d-4+d )/6 => value of s depends on d or c hence
can be -ve or positive
Ans is (E)
