You can
put this solution on YOUR website!Here is the formula for finding the midpoint of co-ordinates(x1,y1) and
co-ordinates(x2,y2)
(x1+x2)/2 ,(y1+y2)/2
so,the answer to ur question would be(mid point of line segment PQ),
(2+3)/2,(-2+4)/2 = 5/2,2/2
that would be (2.5,1),so 2.5 as x co-ordinate and 1 as y co-ordinate..
