Your answer would be choice 3, because when all points of a line lie in a plane, the plain contains the line so the line can contain all of the points. Hope this helped. ;)
You would first apply the Distributive Property to get rid of the parentheses: 216 = -32n + 24 You would then subtract 24 from both sides: 192 = -32n Then you would divide each side of the equation by -32: -6 = n
