distance and midpoints

Question

find the coordinates of the midpoint of a segment with the given endpoints. k(-9,3),h(4,3)

Answer 1

d = SQR[(x2 - x1)^2 + (y2 - y1)^2]

d = SQR(13^2 + 0^2) = SQR(169)

d = 13

kh = 13

midpoint is the mean of both x and y, in this case:

x = (-9 + 4)/2 = -5/2 = -2.5

y = (3 + 3)/2 = 6/2 = 3

midpoint = (-2.5,3)

Answer 2

k(2,3) f(4,4)
