Write the point-slope form of the equation of the line through the given point with the given slope. through: (-1,-2) slope = -5/2

Point-slope form:

y-y1 = m(x-x1)

m = -5/2

x1 = -1

y1 = -2

y - (-2) = -5/2(x-(-1))

y+2 = -5/2(x+1)

y+2=-5/2(x+1)

Step-by-step explanation:

The original point-slope form formula is y-y1=m(x-x1)

So you replace the y1 with the y in the ordered pair, then you replace the m with the slope and then replace the x1 with the x.

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)
