Y=-3/2L -2. At the Y axis, line L is at -2, so we add that as B or the Y intercept. We can see that the graph goes 2 over to the right and down three, which makes the slope negative and 3/2 (rise/run)

Answer:
![\frac{-8 +2\sqrt{3} }{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-8%20%2B2%5Csqrt%7B3%7D%20%7D%7B3%7D)
Step-by-step explanation:
When working with surds we need to take note of the roots present there.
To expand this equation we can do it the following way noting that √3 X √3 = 3
<em></em>
<em>Expanding (1-√3)(⅓+√3)</em>
1 X 1/3 = 1/3
1 X √3 = √3
-√3 X 1/3 =-√3/3
√3 X √3 = 3
hence, expanding the equation, we have
1/3 + √3 -√3/3 + 3
We can simply group the like terms and add them up.
[1/3 +3] +[√3-√3/3]
10/3 + ![\frac{2\sqrt{3} }{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Csqrt%7B3%7D%20%7D%7B3%7D)
= ![\frac{-8 +2\sqrt{3} }{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-8%20%2B2%5Csqrt%7B3%7D%20%7D%7B3%7D)
