In the diagram, δabc is a right triangle with dg⊥cb. what are the coordinates of g? a. (-1, -3)
b. (-0.75, -1.5)
c. (-0.75, -3)
d. (3.75, -2.5)

From the divisions done in the line segment AB, segment CG is also one-fourth of the segment CB. 
        (abscissa)      (6 - -3) / 4 = 2.25
        (ordinate)       (-3 - - 3) / 4 = 0
Add this values to the coordinates of C (-3, -3)
            abscissa   :    -3 + 2.25 = -0.75
            ordinate    :     -3 + 0 = -3
Thus, the coordinate of point G are (-0.75, -3). The answer is letter C. 

The answer would be 16
