Plz which expression is equivalent to the expression below?

What is the point-slope form of theequation for the line with a slope of-2 that passes through (1, 4)? a y + 1 = -2(x + 4)b y-1=-2(x-4)c y + 4 = -2(x + 1)d y - 4 = -2(x - 1)

When turned about its axis of rotation, which shape could have created this three-dimensional object?
