Question 447253
 If the coordinates of A and B are ( x1, y1) and ( x2, y2) respectively, then the midpoint, M, of AB is given by the following formula 																									
(6,-9) 	(-2,7)   																
M ={{{(x1+x2)/2}}}{{{(y1+y2)/2}}}					
x=(6-2)/2,y=(-9	+7)/2												
x= 2,y=	-1																					
Mid point =(2,-1)
