1. Answer:

   Equations are -4x + ky + 7 = 0 ; -2x – y + 2 = 0

   a1 = -4 ; b1 = k ; c1 = 7

   a2 = -2 ; b2 = -1 ; c2 = 2

   The condition for no solution is :

   a1/a2 = b1/b2 ≠ c1/c2

   a1/a2 = -4/-2 = 4/2

   b1/b2 = k/-1

   c1/c2 = 7/2

   a1/a2 = b1/b2 ≠ c1/c2

   4/2 = k/-1 ≠ 7/2

   4/2 = k/-1

   4 × -1 = 2k

   -4 = 2k

   k = -4/2 = -2

   I hope this will help u.please add this to the brainliest.
