Answer:

√72

Step-by-step explanation:

X1=2 Y1=-8 X2=-5 Y2=-2

Distance= √(X2-X1)^2 + (Y2-Y1)^2

= √(-5-2)^2 + (-2-(-8))^2

= √(-7)^2 + (6)^2

= √49 + 36

Answer:

9.22

Step-by-step explanation:

(2,-8) and (-5,-2)

d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2 } \\d=\sqrt{(-5-2)^2+(-2+8)^2} \\d=\sqrt{(-7)^2+(6)^2} \\d=\sqrt{49+36} \\d=\sqrt{85} \\d=9.22 \\
