Question

What is the distance between `(-1,101)` and `(2,-110)`?

Answer 1

`sqrt(44530) = 221.021`

Explanation:

So the distance formula is:

`d=sqrt((y2-y1)^2+(x2-x1)^2`

By plugging in the `x` and `y` values, you should get this:

`d=sqrt((-110-101)^2+(2+1)^2`

Solve.
First, work in the parenthesis.
`sqrt((-211)^2+(3)^2)`
Then, do the rest.
`sqrt(44521+9)`
`sqrt(44530) = 221.021`
