Question

The midpoint of modifying above upper C upper D with bar is E(–1, 0). One endpoint is C(5, 2). What are the coordinates of the other endpoint?

Answer 1

The coordinates of the midpoint of a line segment is the average of the

coordinates of the end points calculation for the coordinates of the other end point are shown below:

abscissa-1=(5+x)/2 ;x=-7

ordinate 0=(2+x)/2 ;y=-2

thus,the co-ordinate of end point is(-7,-2)
