Answer:
The answer is 8.5=(x-2.5)^2+(y-3)^2+(z-4.5)^2
Step-by-step explanation:
First we need to find diameter of the sphere. The distance point A and point B is:

d/2=r=2.92
radius of the sphere is 2.92 units
and the center of the sphere is:
C=((4+1)/2,(3+3)/2,(7+2)/2)
C=(2.5,3,4.5)
We can write the equation of the sphere as:

The expression can be written as:
(2x + 5) - 3
or:
5 + (2x - 3)

and simplified to: "2x + 2" .
_________________________
125 = 5 * 5 * 5 = 5^3
Its a perfect cube.
I’m not sure about the rest but the slope is 4 and the y intercept is 3.
