Segment xy is dilated through point m with a scale factor of 2. which segment shows the correct result of the dilation

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

In which form is the following function written? y = - 2(x – 3)(x + 5)
