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

Answer:

10

Step-by-step explanation:

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

$\sqrt{(x2-x1)^2+(y2-y1)^2}$

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

$\sqrt{(9-1)^2+(8-2)^2}$

Simplify,

$\sqrt{100}$

Rewrite

$\sqrt{10^2}$

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

10

good luck, hope this helps :)
