Question

For what value of k, do the equations 2x – 3y + 10 = 0 and 3x + ky + 15 = 0 represent coincident lines
​

Answer 1

Answer:

for infinite solution we know that,

a¹/a²=b¹/b²=c¹/c²

so, the above pair of equation,

2/3=-3/k

k=-9/2

Answer 2

ANSWER:

k=-9/2

EXPLANATION:

a¹/a²=b¹/b²=c¹/c²

so, the above pair of equation,

2/3=-3/k

k=-9/2
