Three vertices of a square are (–1, 3), (–1, –1), and (3, 3). what is the fourth vertex of the square? a. (–1, –3) b. (1, 3) c. (3, 0) d. (3, –1)

It helps to draw out the problem on a piece of graph paper; if you do, you can see that the fourth point would be directly below (3,3) and directly to the right of (-1,-1), meaning that its coordinates would be (3,-1). A more algebraic method would be to subtract 4, the length of each side of the square, from the y-coordinate of (3,3) and to add 4 to the x-coordinate (-1,-1) to get the same point, (3,-1). 

If i could just have the statements, i'd be able to
