Question

For what value of k, the following system of equations will represent the coincident lines?

x + 2y + 7 = 0
2x + ky + 14 = 0

Answer 1

GIVEN:

To find: To determine for what value of k the system of equation will represents coincident lines

We know that the system of equations

For the system of equation to represent coincident lines we have the following relation

Here,

Hence for the system of equation represents coincident lines
