Question 428529
.


Compare my solution with the solution of the other tutor and find differences



<pre>
Distance between two points	
								
x1	y1	x2	y2						

d= 	{{{sqrt((y2-y1)^2+(x2-x1)^2)}}}								

              12    8    4    2						
			
d= 	{{{sqrt((2-8)^2	+(4-12)^2)}}}	

d= 	{{{sqrt((-6)^2+(-8)^2)}}}

d= 	{{{sqrt(100)}}}				

d= 	10								


........................



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 
									
M ={{{(x1+x2)/2}}}{{{(y1+y2)/2}}}

(	3	,	1	)  	(	7	,	-5	)   				

M =		{{{(x1+x2)/2			}}}	{{{	(y1+y2)/2}}}						

x= 	(	3	+	7	)/	2	y=	(	1	-	5	)/	2

x= 	5		y=	-2
