Answer:
You can do it algebraically by substituting and checking if the inequality is satisfied. You can also do it the graphical way:
The red region is the region where the inequality satisfies.
Plot these:
- A(-1,6)
- B(2,9)
- C(1,-4)
- D(0,0)
- E(-2,-5)
You can see that A and D lie in the region inside the parabola, so they are not a solution.
Rest all are solutions to the inequality.

- A(-1,6) - It is not a solution.
- B(2,9) - It is a solution.
- C(1,-4) - It is a solution.
- E(-2,-5) - It is a solution.
- D(0,0) - It is not a solution.
