Answer 1

Use the distance formula.

Answer 2

what is it?

Answer 3

\(\Large \color{Black}{\Rightarrow d = \sqrt{(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2} }\)

Answer 4

here it will be:

\(\Large \color{Black}{\Rightarrow d = \sqrt{(-1 - 8)^2 + (-1 - 11)^2} }\)

Answer 5

\(\Large \color{Black}{\Rightarrow \sqrt{81 + 144} }\)

\(\Large \color{Black}{\Rightarrow \sqrt{225} }\)

\(\Large \color{Black}{\Rightarrow 15 }\)
