Write the equation of a line in Slope-Intercept Form that has a slope of -3 and a y-intercept of 8.

y=-3x+8

Step-by-step explanation:

Slope intercept is as follows: y=mx+b

m is the slope so replace the m with -3

y=-3x+b

b is the y intercept, so replace the b with 8 (keep in mind that had the y-intercept been negative, we would have subtracted)

This then gives you

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!
