Question

Please see there o it urge below for my homework

Answer 1

Standard form for the equation of a circle is

`(x-h)^2+(y-k)^2=r^2`

Given parameters

`\begin{gathered} r=4 \\ h=-8 \\ k=-7 \end{gathered}`

Substitute the given parameters into the Standard form for the equation of a circle is

`\begin{gathered} (x-h)^2+(y-k)^2=r^2 \\ (x-(-8))^2+(y-(-7))^2=4^2 \\ (x+8)^2+(y+7)^2=16 \end{gathered}`

The final answer

Option A

`(x+8)^2+(y+7)^2=16`
