Question

If the lines given by 3x +2ky=2 and 2x +4y+1=0 are parallel then find value of k

Answer 1

Explanation:

a1/a2 =b1/b2 is not equal to c1/c2

a1 is 3, A2 is 2 ,b1 is 2k , b2 is 4 and c1 is -2 , c2 is 1

3/2=2k/4 is not equal to -2/1

3/2 =2k/4 and 3/2 is not equal to -2/1

3*4=2k*2 ,3*1 is not equal to 2*-2

12=4k ,3 is not equal to -4

k=3 ,-7

so k=3
