Answer:
The coordinate of Midpoint
:((x_1+x_2)/2, (y_1+y_2)/2):(x1+x22,y1+y22) Explanation:
"If "A(x_1,y_1) and B(x_2,y_2) " are the two point on the line ,"If A(x1,y1)andB(x2,y2) are the two point on the line , "then midpoint M of the line segment " bar(AB) " is :"then midpoint M of the line segment ¯¯¯¯¯¯AB is : M((x_1+x_2)/2, (y_1+y_2)/2)M(x1+x22,y1+y22) Please see the image.

Answer:
You find the midpoint in exactly the same way with integers and fractions.
Explanation:
You find the midpoint in exactly the same way with integers and fractions, no matter whether they are common fractions, improper fractions or decimal fractions.
Add the two
xx - values together and divide by22 Add the two
yy -values together and divide by22 This will give a point,
M(x,y)M(x,y) -
If you know one endpoint
(x_1,y_1)(x1,y1) and the midpoint(a,b)(a,b) , but you do not know the other endpoint(x_2,y_2)(x2,y2) , then by rewriting the midpoint formula:{(a={x_1+x_2}/2 Rightarrow 2a=x_1+x_2 Rightarrow x_2=2a-x_1),(b={y_1+y_2}/2 Rightarrow 2b=y_1+y_2 Rightarrowy_2=2b-y_1):} So, the unknown endpoint can be found by
(x_2,y_2)=(2a-x_1,2b-y_1)

The midpoint
M of the points(x_1,y_1) and(x_2,y_2) is found byM=({x_1+x_2}/2,{y_1+y_2}/2) .As you can see above, the each coordinate of
M is the average of the corresponding coordinates of the endpoints.
I hope that this was helpful.
