@Asquare. Yes, you are wrong. If the slope of the line AB equals the slope of the line AC, then points A, B, and C are collinear. One way to look at it is that because AB and AC have the same slope, they are parallel (if you can call coincident lines parallel), and they both contain point A. Therefore, they are coincident.
