What is the the slope that passes through the points (4,-7) and (9,1)

8/5

Step-by-step explanation:

We can use the formula for finding slope for this:  

The answer would be 8/5

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
