The midpoint of the linesegment from P1 to P2 is (4, 1). If P1 equals (4,6)what is P2?
Any help would be great.

> The midpoint of the linesegment from P1 to P2 is (4, 1). If P1 equals (4,6)what is P2?
Find the distance between P1 and the midpoint:
P1  midpoint
(4,6)  (4, 1)
Start with the "x" coordinates. Since the "x" coordinate is the same (x = 4) for both P1 and the midpoint, we know the line is vertical. P2's
"x" coordinate will also equal 4.
Next subtract the "y" coordinates:
P1  midpoint
6  1 = 5
The distance between P1 and the midpoint is 5 coordinate points.
Next subtract 5 from the midpoint's "y" coordinate to find P2.
midpoint  5
1  5 = 4.
P2 = (4, 4)
