7. Find the equations of the following lines: a. passes through (-3, 1) and (6,0) answer in general form and gradient
intercept form

b. i. Parallel and ii.
. perpendicular to a line with gradient -2 and passing
through (-2, 3).

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)
