Question

Distance between (-4,4) and (2,4)

Answer 1

6

Explanation:

Answer 2

For this case we have that by definition, the distance between two points is given by:

`d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}`

We have to:

`(x_ {1}, y_ {1}) = (- 4,4)\\(x_ {2}, y_ {2}) = (2,4)`

Substituting:

`d = \sqrt {(2 - (- 4)) ^ 2+ (4-4) ^ 2}\\d = \sqrt {(2 + 4) ^ 2 + (4-4) ^ 2}\\d = \sqrt {(6) ^ 2 + (0) ^ 2}`

`d = \sqrt {36}\\d = 6`

ANswer:

`d = 6`
