Question

The pair of equations $y=0$ and $y=-7$ has,

• A. One solution
• B. Two solutions
• C. Infinitely many solutions
• D. No solution

Answer 1

The correct option is D

No solution

The explanation for the correct option.

First, we have to draw the pair of equations $y=0$ and $y=-7$on the graph, which is shown below,

From the graph, it is observed that both lines are parallel and parallel lines never intersect to each other.

Therefore, the pair of equations $y=0$ and $y=-7$ has, no solution.

Hence, the option $\left(D\right)$is correct.
