Multiple Choice

Solve the system of equations using substitution.
- $$\left\{ \begin{array} { l } y = - x ^ { 2 } + 3 \\x ^ { 2 } + y ^ { 2 } = 5\end{array} \right.$$

A) x = 1, y = 4; x = 4, y = 19
B) x = 1, y = 2; x = -1, y = 2
C) x = 2, y = -1; x = 1, y = 2; x = -1, y = 2; x = -2, y = -1
D) x = 2, y = -1; x = -2, y = -1
