Question

Suppose you have a line segment with endpoint (-1,2) and midpoint (3,4). Which of the following is the other endpoint of your segment?

Answer 1

Step-by-step explanation:

we know that midpoint of a segment is found from formula

x=(x1+x2)/2

and y=(y1+y2)/2

in this case x=3 and y=4 x2=-1 and y2=2

so x1=2x-x2 =2*3-(-1)=6+1=7

y1=2y-y2=2*4-2=8-2=6

the other endpoint is (7,6)

Answer 2

The correct answer is 7,6
