Question

Find the distance between
(4, 8) and (-2, 2).

Answer 1

6(sqrt(2))

Explanation:

Use the "distance formula" (sqrt((x2-x1)^2 - (y2-y1)^2)), plugging in (4,8) for x1 and y1, and (-2,2) for x2 and y 2

Answer 2

`6√(2)`

Explanation:

Using the distance formula,

`√((4-(-2))^2+(8-2)^2) \\ \\ =√(6^2+6^2) \\ \\ =6√(2)`
