Explanation: use distance formula to solve for d.

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)

d=

(2)

2

+(−2)

d=

4+4

d=

8

d=2

=3.4641…

d=3.5
