If the points (3,1), (3,1), and (2,1) are 3 vertices of a rectangle in the standard (x,y) coordinate plane, what is the fourth vertex? A.) (2,1) B.) (1,3) C.) (1,2) D.) (2,1) E.) (3,1) Notice, in the first two points (3,1) and (3,1), the xcoordinates are the same, and in the points (3,1) and (2,1) the ycoordinates are the same For the fourth point, to make a rectangle, you need to have matching ycoordinates with the point (3,1). Sounds confusing, therefore it's best to graph the given points: (2,1) would be the coordinates of the missing point. D.)
