Find the x and y Intercepts (x-2)^2+(y+8)^2=9

${(x - 2)}^{2} + {(y + 8)}^{2} = 9$

Find the x-intercepts.

To find the x-intercept(s), substitute in $0$ for $y$ and solve for $x$ .

${(x - 2)}^{2} + {((0) + 8)}^{2} = 9$

Solve the equation.

Subtract ${((0) + 8)}^{2}$ from both sides of the equation.

${(x - 2)}^{2} = 9 - {((0) + 8)}^{2}$

Add $0$ and $8$ .

${(x - 2)}^{2} = 9 - 8^{2}$

Raise $8$ to the power of $2$ .

${(x - 2)}^{2} = 9 - 1 \cdot 64$

Multiply $- 1$ by $64$ .

${(x - 2)}^{2} = 9 - 64$

Subtract $64$ from $9$ .

${(x - 2)}^{2} = - 55$

Take the square root of both sides of the equation to eliminate the exponent on the left side.

$x - 2 = \pm \sqrt{- 55}$

Simplify $\pm \sqrt{- 55}$ .

Rewrite $- 55$ as $- 1 (55)$ .

$x - 2 = \pm \sqrt{- 1 (55)}$

Rewrite $\sqrt{- 1 (55)}$ as $\sqrt{- 1} \cdot \sqrt{55}$ .

$x - 2 = \pm \sqrt{- 1} \cdot \sqrt{55}$

Rewrite $\sqrt{- 1}$ as $i$ .

$x - 2 = \pm i \sqrt{55}$

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the $\pm$ to find the first solution.

$x - 2 = i \sqrt{55}$

Add $2$ to both sides of the equation.

$x = i \sqrt{55} + 2$

Next, use the negative value of the $\pm$ to find the second solution.

$x - 2 = - i \sqrt{55}$

Add $2$ to both sides of the equation.

$x = - i \sqrt{55} + 2$

The complete solution is the result of both the positive and negative portions of the solution.

$x = i \sqrt{55} + 2, - i \sqrt{55} + 2$

To find the x-intercept(s), substitute in $0$ for $y$ and solve for $x$ .

x-intercept(s): $None$

Find the y-intercepts.

To find the y-intercept(s), substitute in $0$ for $x$ and solve for $y$ .

${((0) - 2)}^{2} + {(y + 8)}^{2} = 9$

Solve the equation.

Subtract ${((0) - 2)}^{2}$ from both sides of the equation.

${(y + 8)}^{2} = 9 - {((0) - 2)}^{2}$

Subtract $2$ from $0$ .

${(y + 8)}^{2} = 9 - {(- 2)}^{2}$

Raise $- 2$ to the power of $2$ .

${(y + 8)}^{2} = 9 - 1 \cdot 4$

Multiply $- 1$ by $4$ .

${(y + 8)}^{2} = 9 - 4$

Subtract $4$ from $9$ .

${(y + 8)}^{2} = 5$

Take the square root of both sides of the equation to eliminate the exponent on the left side.

$y + 8 = \pm \sqrt{5}$

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the $\pm$ to find the first solution.

$y + 8 = \sqrt{5}$

Subtract $8$ from both sides of the equation.

$y = \sqrt{5} - 8$

Next, use the negative value of the $\pm$ to find the second solution.

$y + 8 = - \sqrt{5}$

Subtract $8$ from both sides of the equation.

$y = - \sqrt{5} - 8$

The complete solution is the result of both the positive and negative portions of the solution.

$y = \sqrt{5} - 8, - \sqrt{5} - 8$

y-intercept(s) in point form.

y-intercept(s): $(0, \sqrt{5} - 8), (0, - \sqrt{5} - 8)$

List the intersections.

x-intercept(s): $None$

y-intercept(s): $(0, \sqrt{5} - 8), (0, - \sqrt{5} - 8)$
