Question

Find the distance between the points (-2, -4) and (-6, -8). Round your answer to to the nearest tenth.

Answer 1

d=5.7

Explanation:

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

`d=\sqrt{-6(-2)^(2)+(-8-(-4)^(2) }`

`d=\sqrt{(-6+2){^(2)+(-8+4)^(2) } }`

d=
`\sqrt{(-4)^(2)+(-4)^(2) }`

d=
`√(16+16)`

d=
`√(32)`

d=5.656 =5.7
