Intercepts of $x^{2} + y^{2} = 9$

Find find the x- and y-intercepts of $x^{2} + y^{2} = 9$.

To find the x-intercepts, substitute $y = 0$ into the equation and solve the resulting equation $x^{2} = 9$ for $x$ (use the equation solver).

To find the y-intercepts, substitute $x = 0$ into the equation and solve the resulting equation $y^{2} = 9$ for $y$ (use the equation solver).

x-intercepts: $\left(-3, 0\right)$, $\left(3, 0\right)$.

y-intercepts: $\left(0, -3\right)$, $\left(0, 3\right)$.
