Answer:
6x + 200 = 17,000
Step-by-step explanation:
Lower level = 4x - 300
Mid level = 2x + 500
Combine the two equations to find the number of seats in the upper level
(2x + 500) × (4x - 300) = 17,000
Combine like terms
4x × 2x + 500 - 300 = 17,000
<em>6x + 200 = 17,000</em>

Answer: ![y=2(x+2)](https://tex.z-dn.net/?f=y%3D2%28x%2B2%29)
Step-by-step explanation:
The slope of the line is
![y=\frac{8-0}{2-(-2)}=\frac{8}{4}=2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B8-0%7D%7B2-%28-2%29%7D%3D%5Cfrac%7B8%7D%7B4%7D%3D2)
Using the point (-2, 0) to substitute into point-slope form, we get the equation to be ![\boxed{y=2(x+2)}](https://tex.z-dn.net/?f=%5Cboxed%7By%3D2%28x%2B2%29%7D)
