There is a line includes the point (0,4) and has a slope of 7 what is its equation in slope-intercept form

the y intercept is 4  (0,4)

slope intercept form

y= mx+b

y=7x+4

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
