Find the midpoint of A and B where A has coordinates (2,9)

timofeeve [1]

Answer:

$(\dfrac{9}{2}, \dfrac{13}{2})$

Step-by-step explanation:

The coordinates of A = (2,9)

The coordinates of B = (7,4)

Let M (x,y) be the mid point of A and B.

$M(x,y)=(\dfrac{x_1+x_2}{2}),(\dfrac{y_1+y_2}{2})\\\\=\dfrac{2+7}{2}, \dfrac{9+4}{2}\\\\=(\dfrac{9}{2}, \dfrac{13}{2})$

So, the coordinates of mid point of A and B is $(\dfrac{9}{2}, \dfrac{13}{2})$ .
