Question

the pair of equation y=0 and y=-7 has​

Answer 1

Answer:

Graphically y = 0 is a straight line which is x - axis and y = - 7 is a straight line parallel to x - axis, 7 units below the origin therefore lines y = 0 and y = - 7 are parallel.

∴ They have no solution.

(because the solution is the intersection point of both the lines).
