Question

If a point A has coordinates (1,2) and point B has coordinates (9,8), what is the distance between points A and B?

Answer 1

10

Explanation:

Use the distance formula to determine the distance between the two points.

`√((x2-x1)^2+(y2-y1)^2) \\`

Substitute the actual values of the points into the distance formula.

`√((9-1)^2+(8-2)^2)`

Simplify,

`√(100)`

Rewrite

`√(10^2)`

Pull terms out from under the radical, assuming positive real numbers.

10

good luck, hope this helps :)
