Question

What is the Midpoint for (-1,1) and (5,-5)

Answer 1

If you have two points (x1,y1) and (x2,y2), the midpoint in between such points is given by:

(xo , yo)

where:

xo = (x1 + x2)/2

yo = (y1 + y2)/2

then, for the points (x1y1) = (-1,1) and (x2,y2) = (5,-5), you have:

xo = (-1 + 5)/2 = 4/2 = 2

yo = (1 - 5)/2 = -4/2 = -2

hence, the midpoint is:

(xo,yo) = (2,-2)
