Question

How many units apart are the points (5, 20) and (10, 8)?

Answer 1

if we move the points so that one of them is at the origin; we should be able to tell how far over and up the other point is and can use the pythag thrm to obtain a result

Answer 2

i prefer distance formula but some people dont like memorizing so learning that is a good idea too

Answer 3

yeah, and that is all the distance formula does; it moves the points and pythags it :)

Answer 4

(5, 20) and (10, 8)
-5-20 -5 -20
-----------------
0 , 0 5 , -12

d^2 = 5^2 + 12^2

d = sqrt(25 + 144)

Answer 5

169?

Answer 6

sqrt(169) but yes
