Question

What is the distance between E(5, 1) and F(7, 10)?

Round to the nearest tenth.

Answer 1

9 is my answer

Answer 2

hint:
we can write this:
\[\begin{gathered}
d = \sqrt {{{\left( {{x_2} - {x_1}} \right)}^2} + {{\left( {{y_2} - {y_1}} \right)}^2}} = \hfill \\
\hfill \\
= \sqrt {{{\left( {5 - 7} \right)}^2} + {{\left( {1 - 10} \right)}^2}} = \hfill \\
\hfill \\
= \sqrt {{{\left( { - 2} \right)}^2} + {{\left( { - 9} \right)}^2}} = ...? \hfill \\
\end{gathered} \]
