Answer
$11.402$ units
Work Step by Step
Step 1: $(-4,-6)=(x_{1},y_{1})$ and $(-1,5)=(x_{2},y_{2})$
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: $d=\sqrt ((-1-(-4))^{2}+(5-(-6))^{2})$
Step 4: $d=\sqrt ((-1+4))^{2}+(5+6)^{2})$
Step 5: $d=\sqrt ((3)^{2}+(11)^{2})$
Step 6: $d=\sqrt (130)\approx 11.402$ units
