Question

Select the points that is a solution

Answer 1

The red area is the one which solves the system. In fact, we want the area which below both the parabola and the line (since the inequality features a
`\leq` sign.

So, the point
`(1,1)` is below the line but above the parabola (blue area), so it is not a solution.

The point
`(2,2)` is above both the line and the parabola (white area), so it is not a solution.

The point
`(-1,0)` is below both the line and the parabola (red area), so it is a solution.

So, the point
`(4,1)` is below the parabola but above the line (green area), so it is not a solution.
