Answer: ![y + 6 = \frac{1}{2}(x - 6)](https://tex.z-dn.net/?f=y%20%2B%206%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%20-%206%29)
Step-by-step explanation:
Point-slope formula: ![y - y1 = m(x - x1)](https://tex.z-dn.net/?f=y%20-%20y1%20%3D%20m%28x%20-%20x1%29)
Plug in the numbers: ![y - -6 = \frac{1}{2}(x-6)](https://tex.z-dn.net/?f=y%20-%20-6%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x-6%29)
Clear the double negatives: ![y + 6 = \frac{1}{2}(x - 6)](https://tex.z-dn.net/?f=y%20%2B%206%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%20-%206%29)
Answer:
