The given points are L(-7,7), and N(-1,2)

We have to use the distance formula


d=√((y_2-y_1)^2+(x_2-x_1)^2)

Replacing the given points, we have


\begin{gathered} d_(LN)=√((2-7)^2+(-1-(-7))^2) \\ d_(LN)=√((-5)^2+(-6)^2)=√(25+36)=√(61) \\ d_(LN)\approx7.8 \end{gathered}

Therefore, the distance is 7.8, approximately.

However, an exact answer would be "the distance is the square root of 61".
