Question

What is the distance from the point (0,-4) to point (4,4)?

Answer 1

Answer: d=8.9

Explanation:

√80=8.9

Answer 2

Answer: Distance is 8.9

Explanation:

`d = √((x2-x1)2 + (y2-y1)2)`

`(x2-x1) = (4 - 0) = 4`

`(y2-y1) = (4 -4) = 8`

Add it all together

`(4)2 + (8)2 = 16 + 64 = 80`

Square 80

`√(80) =4√(5) \\=8.9443`
