Question

Find the distance between the points P1 = (3,-1) and P2 = (-1,-4)

Answer 1

You're familiar with Pythagorean Theorem, right?

Answer 2

yes but I am not allowed to use graph

Answer 3

Well, then you'll have to use the distance formula

\[D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\]

Answer 4

thats the Pythagorean Theorem ?

Answer 5

So compute this:

\[D = \sqrt{(3 - (-1))^2 + (-1 - (-4))^2}\]

Answer 6

Distance formula is derived from Pythagorean Theorem.

Answer 7

aaah

Answer 8

thx <33 :)
