Question

What is the distance between the points (5, –6) and (5, 2)?

A.
1

B.
3

C.
4

D.
8

Answer 1

use the pythegorean theorem, the difference from x1 to x2 is a side of a triangle, the difference from y1 to y2 is the other side, so the distance between the two points is the is the hypotenuse
(5-5)^2 + (-6-2)^2 = (d)^2
0 + 64 = d^2
d = sqrt(64) = 8
