Substitute (1,2) into the equation,
LHS = 2
RHS = 1^2-3
=-2
LHS not equal to RHS
Therefore (1,2) does not satisfy the equation
Substitute (4,13) into the equation,
LHS = 13
RHS = 4^2-3
=13
LHS=RHS
Therefore, (4,13) satisfies the equation
Substitute (-3,-9) into the equation,
LHS = -9
RHS = (-3)^2-3
=6
LHS not equal to RHS
Therefore, (-3,-9) satisfies the equation
Substitute (-5,22) into the equation,
LHS = 22
RHS = (-5)^2-3
=22
LHS=RHS
Therefore (-5,22) satisfies the equation
