Question

. The pair of equation = 0 and = −7 has _________ solutions.​

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 solution is the intersection point of both the lines)
