Question

Find the distance for the following points A ( -2, -3) B (-7, -8). If necessary round your answer to the nearest tenth.

(this math is killing me)

Answer 1

yeah it is a pain

Answer 2

Use the distance formula:

sqrt((-2 - (-7))^2 + (-3 - (-8))^2)
= sqrt( 25 + 25) = 5sqrt(2).

Answer 3

1)
11
2)
7.1
3)
7
4)
-7.1

Answer 4

\[\sqrt{(-2--7)^{2}+(-3--8)^{2}}\]\[\sqrt{5^{2}+5^{2}}=\sqrt{50}=5\sqrt{2}=7.07\]
Choice 3 is the closest.
