Answer
[tex]2\sqrt{10}[/tex]
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
[tex]\sqrt{(x^2-x^1)^2 + (y^2 - y1)^2}[/tex]
2. Plug in the numbers into the formula:
1 -(-1)^2 + 3 - (-3)^2
[tex]2^2=4[/tex]
[tex]6^2 = 36[/tex]
36 + 4 = 40
3. Find the square root of 40.
[tex]\sqrt{40}[/tex]
Simplify further:
[tex]2\sqrt{10}[/tex]
