Square OCAB has an area of 9 square units. Point O is found where the axes meet. What are the coordinates of point A?  Pick one
A) (3, 1)
B) (3, 2)
C) (3, 3)
D) (3, 4)
E) None
Solution:   If the square has an area of 9 square units, then its side has a length of 3 units. If O is where the axes meet, then points C and B are found on the x- and y-axes and they have the coordinates (3, 0) and (0, 3). Point A is at 3 units from the x-axis and at 3 units from the y-axis and it has the coordinates (3, 3).   Answer (3, 3)
