16. Find the coordinates of point C if B(-3, 1) is the midpoint of segment AC 1 and point A has coordinates (1,7).

(-7, -5)

Step-by-step explanation:

Point A is at (1,7) and point B is at (-3,1). To get from the x-coordinate of A to the x-coordinate of B, you have to move right 4, or you have to subtract 4 from the x-coordinate of point A. To get to the x-coordinate of point C, you must do the same since B is the midpoint. -3 - 4 is -7. To get from the y-coordinate of A to the y-coordinate of B, you have to move down 6, or you have to subtract 6 from the y-coordinate of point A. 1 - 6 is -5.

The coordinates of point C are thus (-7,-5).
