Question

Find the distance between the points: (-3, 3) and (3, -3). If necessary, round your answer to two decimal places.

Answer 1

Given two points (x1,y1) (x2,y2) the distance formula is

\[d=\sqrt{(x2-x1)^2+(y2-y1)^2}\]

can you plug the points in?

Answer 2

If that formula looks vaguely familiar, this diagram might give you a clue as to why:

Answer 3

\[x_2-x_1\] gives the length of the leg labeled b and \[y_2-y_1\] gives the length of the leg labeled a
