Question

the value of K such that 3x+4y+5_K(x+y+3)=0 is parallel to y_axis​

Answer 1

Answer:

The equation can be rewritten as

$(3 - k)x \: + (4 - k)y + 5 - 3k = 0$

Since line is parallel to y - axis, it means equation of line donot have term of y.

So, Coefficient of y = 0

so 4 - k = 0

k = 4
