see condition for parallel lines is:--
a1/a2 = b1/b2 ≠c1/c2
l------------------l
taking this....
2/k = -3/-9
2/k =1/3
2*3 = k
k = 6
a1/a2 = b1/b2 ≠c1/c2
l------------------l
taking this....
2/k = -3/-9
2/k =1/3
2*3 = k
k = 6
thank you for answer

2x - 3y = 9 → y = (2/3) x - 3
kx - 9y = 18→ y = (k/9) x - 2
Parallel = Same Slope
(2/3) = (k/9)
k = 6
kx - 9y = 18→ y = (k/9) x - 2
Parallel = Same Slope
(2/3) = (k/9)
k = 6
