Question
If the line
(3x+14y+7)+k(5x+7y+6)=0
is parallel to the y-axis, then the value of k is
(3x+14y+7)+k(5x+7y+6)=0
is parallel to the y-axis, then the value of k is
Answer: Option C
:
C
Given line is (3x+14y+7)+k(5x+7y+6)=0
⇒(3+5k)x+(14+7k)y+(7+6k)=0
If it is parallel to y- axis, thencoefficient of y =0
⇒14+7k=0
⇒k=−2
