Use the distance formula.

The distance between two points $\displaystyle (x_1,y_1)$ and $\displaystyle (x_2,y_2)$ is given by

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

now, can you do your problem?

the distant between $\displaystyle A(x_o,y_o) ,B(x_1,y_1)$ given by

$\displaystyle Distance=\sqrt{(x_1-x_o)^2+(y_1-y_o)^2}$

Edit:someone reply before me ...
