The midpoint of ab is M (-6,1 ). if the coordinates of A are (-7,-3 ),what are the coordinates of B
Scrat [10]

Answer:

B(-5,5).

Step-by-step explanation:

It is given that midpoint of AB is M (-6,1).  

Coordinates of A are (-7,-3 ).

We need to find the coordinates of point B.

Let coordinates of point B are (a,b).

Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

Midpoint of AB is

Midpoint=\left(\dfrac{-7+a}{2},\dfrac{-3+b}{2}\right)

(-6,1)=\left(\dfrac{-7+a}{2},\dfrac{-3+b}{2}\right)

On comparing both sides, we get

\dfrac{-7+a}{2}=-6

-7+a=-12

a=-12+7

a=-5

\dfrac{-3+b}{2}=1

-3+b=2

b=2+3

b=5

Therefore, the coordinates of B are (-5,5).
