The coordinates of endpoint d in cd are at d (5,5).if the midpoint of the segment is at m(1,_1)what are the coordinates of point c?

The required points of the given line segment  are ( - 3, - 7 ).

Step-by-step explanation:

Given that the line segment CD whose midpoint M is ( 1, - 1 ) and point D is ( 5, 5 ), then we have to find point C of the line segment CD-

As we know that-

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

C = ( , )

Here,

Let C ( x, y ), D ( 5, 5 ) with midpoint M ( 1, -1 )-

then by the midpoint formula-

( 1, -1 )  = ( ,  

On comparing x coordinate and y coordinate -

We get,

( = 1  , = -1 )

( x + 5 = 2, y + 5 = - 2 )

( x = 2 - 5,  y = -2 - 5 )

( x = - 3,  y = -7 )

Hence the required points  C are (- 3, - 7 ).

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

70,000 + 6,000 + 800 + 30
