$sqrt(5)$

Explanation:

The distance between two points $(x_1,y_1)$ and $(x_2,y_2)$
is given by the Pythagorean Theorem as
$color(white)("XXX")d= sqrt((x_2-x_1)^2+(y_2-y_1)^2)$

In this case
$color(white)("XXX")d= sqrt(2^2+(-1)^2) = sqrt(5)$

The relationship between the point can be seen in the image below:
