Question

Find the distance from point a (7/8, -1/8) to point b (-1/8, 7/8)

Answer 1

sqrt(2) ≈1.414213562

Explanation:

Distance is found by the formula

d =sqrt ( (x2-x1)^2 + (y2-y1)^2)

= sqrt( (-1/8 - 7/8)^2 + (7/8 --1/8)^2)

sqrt( (-8/8)^2 + (7/8 +1/8)^2)

sqrt( (-1)^2 + (1)^2)

sqrt ( 1 +1)

sqrt(2)
