SOLUTION: Points A, B, C, and D are located on a line. A is at (-6,13), D is at (2, 14), C is the midpoint of the line AD and B is the midpoint of AC. What is the sum of the coordinates of p

Question 1068539: Points A, B, C, and D are located on a line. A is at (-6,13), D is at (2, 14), C is the midpoint of the line AD and B is the midpoint of AC. What is the sum of the coordinates of point B? Express the answer as a common fraction.

Midpoint of AD is average of each coordinate or (-2,13.5), which is C
The average of the coordinates of AC are the average of the x and y coordinates
(-6,13) and (-2, 13.5)
That is -4 and 13.25
They add to 9 1/4 or 37/4.
