You can put this solution on YOUR website! The fourth vertex is (-1, 2). All four of the coordinates will share 1 x value and 1 y value with another one, which is what makes it a square/rectangle. This is the only combination that hasn't been done yet, and if you'll graph it you'll see that the point is in fact at (-1,2).
Hope I helped!
