Write an equation in point slope form for the line that passes through the given point and is perpendicular to the graph of each equation. (-2,5); Y-1=-1/3(x-4)

y = 3x + 11

Step-by-step explanation:

You need to find the negative reciprocal of the original line's slope and use the point-slope formula to find the line that is perpendicular to y-1 = -1/3(x-4).

Point-Slope Formula:

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)
