CD has endpoints C and D, with C at coordinates (5,8). CD has midpoint M at (3,9).
What are the coordinates of point D?

I thought it was (1, 10) but apparently it's not
Answered by oobleck
(1,10) is correct.
Answered by mika

Answered by oobleck
even texts and online tests have mistakes.
Better take it up with your teacher.
