Intercepts of $$$x^{2} + y^{2} = 16$$$

The calculator will find the the x- and y-intercepts of $$$x^{2} + y^{2} = 16$$$, with steps shown.
Like x+2y=3, y=2x+5 or x^2+3x+4.

Your Input

Find find the x- and y-intercepts of $$$x^{2} + y^{2} = 16$$$.

Solution

To find the x-intercepts, substitute $$$y = 0$$$ into the equation and solve the resulting equation $$$x^{2} = 16$$$ for $$$x$$$ (use the equation solver).

To find the y-intercepts, substitute $$$x = 0$$$ into the equation and solve the resulting equation $$$y^{2} = 16$$$ for $$$y$$$ (use the equation solver).

Answer

x-intercepts: $$$\left(-4, 0\right)$$$, $$$\left(4, 0\right)$$$.

y-intercepts: $$$\left(0, -4\right)$$$, $$$\left(0, 4\right)$$$.
