Question

Find the distance between the two points.

Answer 1

Answer

$2\sqrt{10}$

Explanation

1. Use Distance formula

Important to use distance formula in such problems, so keep this formula memorized for future use.

The formula to find distance amongst two points is

$\sqrt{(x^2-x^1)^2 + (y^2 - y1)^2}$

2. Plug in the numbers into the formula:

1 -(-1)^2 + 3 - (-3)^2

$2^2=4$

$6^2 = 36$

36 + 4 = 40

3. Find the square root of 40.

$\sqrt{40}$

Simplify further:

$2\sqrt{10}$
