hartnn · Answer

can you find the co-ordinates of p and Q ?

anonymous · Answer

Yes. Can you give me a second to get them please.

anonymous · Answer

(-2,10) = P
(8,-4) = Q

hartnn · Answer

Q is correct.
for P, -2 is correct, try again for y-co-ordinate..

anonymous · Answer

My bad. 
(-2,8) = P

hartnn · Answer

correct, now the mid-point given 2 endpoints will be just the average of the co-ordinates of endpoints.
so, x=(x1+x2)/2
y=(y1+y2)/2
just plug in values.

anonymous · Answer

Oh!
Okay, Thank You so much :)

hartnn · Answer

so, what you got mid-point as ? 
just to verify.

anonymous · Answer

Give me a second to calculate it.

hartnn · Answer

sure. take your time  :)

anonymous · Answer

I got:
(-2,8) = P
(8,-4) = Q
X = (-2+8)/2
Y = (8+-4)/2
X = 3
Y = 2

anonymous · Answer

So (3,2) aka A :D
