Question

Maximum 98 points to answer

Find the distance between the points.
(1/2, 2/3) and (1,-1)

Answer 1

ref: distance formula
(y1-y2)^2 + (x1+-x2)^2 = (distance)^2
doesn't matter in which order you subtract x and y
(1-1/2)^2 + (-1-2/3)^2 = 3.028 = distance^2
Approximate distance = 1.514

Answer 2

distance formula =

(y1-y2)^2 + (x1+-x2)^2 = (distance)^2

(1-1/2)^2 + (-1-2/3)^2 = 3.028 = 1.514 which is equal to sqrt(109)/6
