Having trouble finding the slope.

I think slope = -8/3

Step-by-step explanation:

I took 2 perfect point

( 1;4) , ( 4; -4)

apply the formula

-4-4/4-1=-8/3

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!
