Answer:
k=3
Step-by-step explanation:
see for an equation to represent parallel lines the condition is,
a1/a2 = b1/b2 ≠ c1/c2
where all these are coefficient of each term
Here,
If k = -3
a1/a2 = 2/4 = 1/2 equal to b1/b2 = 3/6 = 1/2 not equal to c1/c2 = 3/-(-3) = 1
Therefore, a1/a2 = b1/b2 ≠ c1/c2 and now, it will represent parallel lines
