SOLUTION

Let us obtain the coordinates of the point representing Jane's house;


ie\text{ \lparen-5,-2\rparen}

The coordinates of the friend's house is given as;


ie\text{ \lparen3,-4\rparen}

Now, the formula for calculating the distance between two points is given as;


Distance=√((x_2-x_1)^2+(y_2-y_1)^2)
\begin{gathered} Distance=\text{ }√((3-(-5))^2+(-4-(-2))^2) \\ Distance=\text{ }√(8^2+(-2)^2)=√(64+4)\text{ =}√(68)=\text{ }√(4*17)\text{ =2}\sqrt{17\text{ }}units \end{gathered}

THE DISTANCE BETWEEN THE HOUSES IS:


2√(17)\text{ }units
