Answer:
y= -4x+1
Step-by-step explanation:
If you want to write this equation in slope intercept form, you need to find the y-intercept. Here is your current equation y= -4x + b. Then, substitute the x and y for the coordinate. Now, it should look like this: 9= -4(-2) + b. Multiply -4 and -2 to get 8. Now, this is your equation: 9= 8 + b. Then, subtract 8 from both sides to get your final answer, 1=b. Now that you have your y-intercept, go back to your original equation and fill in 1 for b. This is your final equation: y= -4x+1. Hope this helped!

Volume of a Sphere Formula: ![\displaystyle V = \frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Volume <em>V</em> = 797 ft³
<u>Step 2: Solve for </u><em><u>r</u></em>
- Substitute in variables [Volume of a Sphere Formula]:
![\displaystyle 797 \ ft^3 = \frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=%5Cdisplaystyle%20797%20%5C%20ft%5E3%20%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
- [Division Property of Equality] Isolate <em>r</em> term:
![\displaystyle \frac{2391}{4 \pi} \ ft^3 =r^3](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B2391%7D%7B4%20%5Cpi%7D%20%5C%20ft%5E3%20%3Dr%5E3)
- Rewrite:
![\displaystyle r^3 = \frac{2391}{4 \pi} \ ft^3](https://tex.z-dn.net/?f=%5Cdisplaystyle%20r%5E3%20%3D%20%5Cfrac%7B2391%7D%7B4%20%5Cpi%7D%20%5C%20ft%5E3)
- [Equality Property] Cube root both sides:
![\displaystyle r = \frac{4782^{\frac{1}{3}}}{2 \pi^{\frac{1}{3}}} \ ft](https://tex.z-dn.net/?f=%5Cdisplaystyle%20r%20%3D%20%5Cfrac%7B4782%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%7D%7B2%20%5Cpi%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%7D%20%5C%20ft)
- Evaluate:
![\displaystyle r = 5.75162 \ ft](https://tex.z-dn.net/?f=%5Cdisplaystyle%20r%20%3D%205.75162%20%5C%20ft)
- Round:
![\displaystyle r \approx 5.8 \ ft](https://tex.z-dn.net/?f=%5Cdisplaystyle%20r%20%5Capprox%205.8%20%5C%20ft)
