For the point P (-16, 25) and Q (-11, 28) find the distance d (P, Q) and the coordinates of the midpoint M of the segment PQ.

Answer 1

Use the Pythagorean Theorem

d^2 = (5)^2 + (3)^2 = 25+9 = 34

d = sqr34 = about 5.831

midpoint M = is the average of the x coordinates and the average of the y coordinates

(-13 1/2, 26 1/2)

or (-13.5, 26.5) = M
