Question

what is the midpoint of the line segment that runs between (-3,1) and (1,5)

Answer 1

(-3+1)/2 and )1+5)/2

-1 and 3

(-1,3)

Answer 2

(-1,3)

X = (-3 + 1) / 2 = (-2/2) = -1

Y = (1 + 5) / 2 = (6/2) = 3

Answer 3

To determine the midpoint, you average the x values and average the y values

(-3 +1)/2 = -2/2 = -1

(1+5)/2 = 6/2 = 3

The midpoint is (-1,3)
