$8.544$ units
Step 1: $(-1,5)=(x_{1},y_{1})$ and $(2,-3)=(x_{2},y_{2})$ 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: $d=\sqrt ((2-(-1))^{2}+(-3-(5))^{2})$ Step 4: $d=\sqrt ((2+1))^{2}+(-8)^{2})$ Step 5: $d=\sqrt ((3)^{2}+(-8)^{2})$ Step 6: $d=\sqrt (73)\approx 8.544$ units
