Question

The distance AB rounded to the nearest tenth
(-2, 1) and (1,-1)

Answers

  1. Answer:

    it gives you the formula, so all you have to do is plug in the coordinates

    \begin{gathered}d = \sqrt{ {( – 1 + 3)}^{2} + {( – 1 – 1)}^{2} } \\ d = \sqrt{ {(2)}^{2} + {( – 2)}^{2} } \\ d = \sqrt{ 4 + 4 } \\ d = \sqrt{8} \\ d = 2 \sqrt{3} = 3.4641… \\ \\ d = 3.5\end{gathered}

    d=

    (−1+3)

    2

    +(−1−1)

    2

    d=

    (2)

    2

    +(−2)

    2

    d=

    4+4

    d=

    8

    d=2

    3

    =3.4641…

    d=3.5
