A point is a solution of the system if it lies in the overlapped region. Since the parabolas are dashed, a point that is *on* any of the curves is **not** a solution. Let's arbitrarily plot two points in the overlapped area.

The points $(2,0)$ and $(3,0)$ lie in this region. Therefore, these points are solutions of the system. Note that $(2,0)$ and $(3,0)$ are only two of the infinitely many solutions.

Notice that both points lie on the parabolas. Since the parabolas are dashed, the solution set does not include points *on* the curves. Therefore, the points $(1,-2)$ and $(5,6)$ are **not** solutions of the system.
