#### Answer

$14.036$ units

#### Work Step by Step

Step 1: $(-6,3)=(x_{1},y_{1})$ and $(8,4)=(x_{2},y_{2})$
Step 2: The distance between two points is found by the formula,
$d=\sqrt ((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2})$
Step 3: $d=\sqrt ((8-(-6))^{2}+(4-3)^{2})$
Step 4: $d=\sqrt ((8+6))^{2}+(4-3)^{2})$
Step 5: $d=\sqrt ((14)^{2}+(1)^{2})$
Step 6: $d=\sqrt (197)\approx 14.036$ units
