Question

A. Your two points are (5,9) and (2, 1). Find the distance between the two
points.

Answer 1

Root of 73 ~ 8.544

Explanation:

d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}

d = distance

(x_1, y_1) = coordinates of the first point

(x_2, y_2) = coordinates of the second point

That is your formula
