Question

Find the distance
(-5,8) (2,-5)

Answer 1

So here we are basically finding a hypotenuse. So we have...

a^2+b^2=c^2

We have a and b of the sides, a is the distance of x, b is the distance of y. So...
a=7
b=13

So if we put that in to our theorem, we get this.

7^2+13^2=c^2

Make sense?

Answer 2

good try @Headdesk ! unfortunately, pythagorean theorem is for triangles yes? this is the distance between two points.

Answer 3

Actually if you look at we do...

make sense now?
