Question

Find the length of the line segment between points A(-2,8) and B(5,-1)

Answer 1

D ≈ 11.402

Explanation:

We'll need the distance equation for this problem:

D =
`\sqrt{(x2-x1)^2+(y2-y1)^2`

D =
`√(((5 - (-2))^2+(-1-8)^2)`

D =
`√((7)^2+(-9)^2)`

D =
`√(49+81)`

D =
`√(130)`

D ≈ 11.402
