The equation of the tangent line is:![\boxed{\textsf{y = -2x}} \boxed{\textsf{y = -2x}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctextsf%7By%20%3D%20-2x%7D%7D)
The equation of the normal line is:![\boxed{\mathsf{y=\dfrac{1}{2}x-5}} \boxed{\mathsf{y=\dfrac{1}{2}x-5}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cmathsf%7By%3D%5Cdfrac%7B1%7D%7B2%7Dx-5%7D%7D)
