Question

The pair of lines represented by the equations 2x+y+3=0 and 4x+ky+6=0 will be parallel if value of k is _____​

Answer 1

Answer:

put the formula i.e. a1/a2 and so on .then put the à1/a2 =c1c2

Answer 2

Step-by-step explanation:

For parallel condition of two lines,

2/4= 1/k # 3/6

Now, 2/4= 1/k

or, 1/2= 1/k

or,k = 2.

So, the value of k is 2.
