Step-by-step explanation:
(1) The radius of sphere is 4.5 units.
The volume of volume of sphere is given by :
![V=\dfrac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
![\pi=3.14\ , r=4.5](https://tex.z-dn.net/?f=%5Cpi%3D3.14%5C%20%2C%20r%3D4.5)
So,
![V=\dfrac{4}{3}\times 3.14\times (4.5)^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%203.14%5Ctimes%20%284.5%29%5E3)
Option C is correct.
(2) If we solve the plugged values, then we get :
![V=\dfrac{4}{3}\times 3.14\times (4.5)^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%203.14%5Ctimes%20%284.5%29%5E3)
![V=381.5\ \text{units}^3](https://tex.z-dn.net/?f=V%3D381.5%5C%20%5Ctext%7Bunits%7D%5E3)
Option C is correct.
Answer:
![11. \: slope \: = 0](https://tex.z-dn.net/?f=11.%20%5C%3A%20slope%20%5C%3A%20%20%3D%200)
![12. \: undefined](https://tex.z-dn.net/?f=12.%20%5C%3A%20undefined)
![13. \: undefined](https://tex.z-dn.net/?f=13.%20%5C%3A%20undefined)
![for \: y = 3 \: draw \: a \: straight \: line \: across \: 3](https://tex.z-dn.net/?f=for%20%5C%3A%20y%20%3D%203%20%5C%3A%20draw%20%5C%3A%20a%20%5C%3A%20straight%20%5C%3A%20line%20%5C%3A%20across%20%5C%3A%203)
![for \: y = 3x \: draw \: a \: diagonal \ \: line \: across \: 0](https://tex.z-dn.net/?f=for%20%5C%3A%20y%20%3D%203x%20%5C%3A%20draw%20%5C%3A%20a%20%5C%3A%20diagonal%20%5C%20%5C%3A%20line%20%5C%3A%20across%20%5C%3A%200)
14. the difference is that in y=3 there is a y-intercept, the equation does not have a slope neither does the graph.
In y=3x the equation has a slope but no y-intercept.
If you have any questions ask me in the comments.
I've attached 2 images that demonstrate this.

Answer: C
Step-by-step explanation:
Using the point-slope form formula, y - y1 = m(x - x1), you would plug in the slope and the points.
