Question

How do you find the missing coordinate if the 1st coordinate is (-6, -1) and midpoint is (-1,1)?

Answer 1

Missing coordinate (end point) is `(4,3)`

Explanation:

Let the missing coodinate (end point) is (x,y)
The first coordinate(start point) is `(-6,-1)` and the mid point is `(-1,1)` we know the mid point is average of start and end point.
`:. -1 = (x+(-6))/2 or x=-2+6=4` and `1= (y +(-1))/2 or y= 2+1=3` So missing coordinate (end point) is `(4,3)` [Ans]
