\begin{gathered} y=x^2-3 \\ For\text{ (1,2)} \\ x=1,\text{ y=2} \\ y=1^2-3 \\ y=1-3 \\ y=-2,\text{ -2}\\e2,\text{ hence} \\ \text{ this pair doesnt satisfy the equation }y=x^2-3 \\ \text{For (}4,13\text{)} \\ x=4,y=13 \\ y=4^2-3 \\ y=16-3 \\ y=13,\text{ 13=13, hence} \\ \text{This pair satisfies the equation }y=x^2-3 \\ \text{for (}-3,-9\text{)} \\ x=-3,\text{ y=-9} \\ y=(-3)^2-3 \\ y=9-3 \\ y=6,\text{ -9}\\e6,\text{ hence} \\ \text{ this pair doesnt satisfy the equation }y=x^2-3 \\ \text{For (}-5,22\text{)} \\ x=-5,\text{ y=22} \\ y=(-5)^2-3 \\ y=25-3 \\ y=22,\text{ 22=22, hence} \\ \text{This pair satisfies the equation }y=x^2-3 \end{gathered}
