Question

If the lines given by 3x+ 2ky = 2 and 2x + 5y + 1 = 0, are parallel then the value of K is *

1 point

a) -5/4,

b) 2/5,

c) 3/2

d) 15/4

​

Answer 1

As the lines are parallel ,so the eqs.have no sol.

which means a1/a2=b1/b2 not equal to c1/c2

here a1=3,b1=2k,a2=2,b2=5

3/2=2k/5

5×3/2×2=k

15/4=k
