Answer: (a)
Step-by-step explanation:
a1 = k
b1 = -1
c1 = -2
a2 = 6
b2 = -2
c2 = -3
for no sol.
a1/a2 equals b1/b2 not equals c1/c2
equating a1/a2 = b1/b2
k/6 = -1/-2
by cross multiplying,
-2k = -6
k = 3

Answer:
By using ratio,
K/6 = -1/-2 = -2/-3
a¹/a² = b¹/b² ≠ c¹/c²
Thus, this sum is parallel graphic representation. Answer A) 3 seems to be the appropriate option.
