Ab is m(3,-2). one endpoint is a(7,-9). find the coordinates of the other endpoint b.

The required points of the given line segment  are ( - 1, - 5 ).

Step-by-step explanation:

Given that the line segment AB whose midpoint M is ( 3, -2 ) and point A is ( 7, - 9), then we have to find point B of the line segment AB -

As we know that-

If a line segment AB is with endpoints ( ) and  (  ) then the mid points M are-  

M = (  , )

Here,

Let A ( 7, - 9 ), B ( x, y ) with midpoint M ( 3, - 2 ) -

then by the midpoint formula M are-

( 3, - 2 )  = (   , )

On comparing x coordinate and y coordinate -

We get,

( = 3  ,  = - 2)

( 7 + x = 6, - 9 + y = - 4 )

( x = 6 - 7, y = - 4 + 9 )

( x = - 1, y = -5 )

Hence the required points  A are ( - 1, - 5 ).

We can also verify by putting these points into Midpoint formula.
