Question

Which of the following choices is the length of AB if A (-3, -2) and B (5, -4)?

Answer 1

\sqrt{68}

Explanation:

Using the distance formula, you can find that the distance between these two points is:

`√((5-(-3))^2+(-2-(-4))^2)=\\\\√((5+3)^2(-2+4)^2)=\\\\√(8^2+2^2)=√(64+4)=\\\\\boxed{√(68)}`

This is based on the Pythagorean Theorem, since you can imagine making a right triangle between these two points and the distance between them being the hypotenuse. Hope this helps!
