Answer

6.7 miles

Work Step by Step

We know that Oak=(-1,-2) and Jackson=(2,4). To find the distance, use the Distance Formula which is $\sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }$. Substituting gives $\sqrt {\left( {-1 - 2 } \right)^2 + \left( {-2 - 4 } \right)^2 }=\sqrt {\left( {-3 } \right)^2 + \left( {-6 } \right)^2 }=\sqrt {9+36}=\sqrt {45}=6.7$
