Question 426762
This is what I'm suppose to do - If P is the midpoint of line segment AB, find the coordinates of the missing point A,B, or P. 
Please help me solve this --->A(3,5),P(11,7)
-----------------
Let P have coordinates (x,y)
--
Then:
(x+3)/2 = 11
x+3 = 22
x = 19
---
(y+5)/2 = 7
y+5 = 14
y = 9
---
Ans: P(19,9)
