pls answer this question The pair of equations y 0 and y (a) one solution (b) two solution -7 has (c) infinitely many solutions (d) no solution

Dear student
The equation y = 0 represents  x-axis and the equation y = -7  also represent a straight line parallel to x-axis and 7 units below the line y = 0.

We know that if two lines are parallel to each other then they don't possess any common solution. So, the pair of equations y = 0 and y = -7 don't have any common solution.
