Question

Find the distance of AB given A(2,-8) B(-5,-2)

Answer 1

√72

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

= ✓85

Answer 2

9.22

Explanation:

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

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