![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Step-by-step explanation:
<u>Step 1: Define</u>
Point (-11, 6)
Point (-7, 2)
<u>Step 2: Find slope </u><em><u>m</u></em>
Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>
- Substitute [SF]:
![m=\frac{2-6}{-7+11}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2-6%7D%7B-7%2B11%7D)

Answer:
Step-by-step explanation:
s and r are the arc length and radius, respectively.
perimeter of sector = s+2r = 8
s = 8-2r
θ = s/r = (8-2r)/r
