point a is located at (1, 5) and D is located at (3, 7). find the coordinate of the point that lies half way between A and D.
OpenStudy (danjs):
The midpoint on a line connecting 2 points , is just the sum of the coordinates divided by 2
OpenStudy (danjs):
(x1+x2)/2 and (y1+y2)/2
OpenStudy (anonymous):
Ok give me one minute to solve :)
OpenStudy (danjs):
Ill do the X real fast, you do the Y...
midpoint of the x coordinate
(1 + 3) / 2 = 4/2 = 2

Midpoint so far
(2, y)
OpenStudy (anonymous):
5=7=12/2=6 Sooo, (2, 6)
OpenStudy (danjs):
you have the point right, all those = signs are not though
OpenStudy (danjs):
i know you meant +
OpenStudy (danjs):
(5+7)/2 = 12/2 = 6

yeah haha opps
OpenStudy (anonymous):
yes
OpenStudy (danjs):
\[midpoint = (\frac{ x1+x2 }{ 2 } ~,~\frac{ y1+y2 }{ 2 })\]
OpenStudy (anonymous):
We only have one coordinate though, do I use the original ones?

That is the midpoint formula , given 2 points (x1,y1) and (x2,y2)
OpenStudy (anonymous):
sorry I see now haha my answer choices arent that though.
OpenStudy (anonymous):
I have (-3, 4) (-1, 6) (1, 6) And (3, 4)
OpenStudy (danjs):
the average of the x coordinates, and average of the y coordinates
OpenStudy (anonymous):
so would it be 1,6?

can you type the original 2 points out again please
OpenStudy (anonymous):
A is located at (1, 5), and D is located at (−3, 7)
OpenStudy (danjs):
oh, it is a -3, you had it as +3 originaly
OpenStudy (anonymous):
yeah, sorry haha
OpenStudy (danjs):
\[midpoint = (\frac{ 1+(-3) }{ 2 }, \frac{ 5+7 }{ 2 })\]
