#### Answer

$2\sqrt{2} \approx 2.83$ units

#### Work Step by Step

RECALL:
The distance between the points $(x_1, y_1)$ and $(x_2, y_2)$ can be found using the distance formula
$d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$
Use the formula above to obtain:
$d=\sqrt{(6-4)^2+(3-1)^2}
\\d=\sqrt{2^2+2^2}
\\d=\sqrt{4+4}
\\d=\sqrt{8}
\\d=\sqrt{4(2)}
\\d=\sqrt{2^2(2)}
\\d=2\sqrt{2}
\\d \approx 2.83$
