Question

What is the formula to find the distance between two points?

Answer 1

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

Answer 2

Thank you!

Answer 3

it is pythagoras.
\[a^2+b^2=c^2\] where
\[a=x_2-x_1,b=y_2-y_1\] so you get
\[\sqrt{(x_1-x_2)^2+(y_2-y_1)^2}\] for the distance

Answer 4

yeah waat she said
