To answer this question we will use the following formula to compute the distance between two given points (x,y) and (v,w):


d=√((x-v)^2+(y-w)^2).

From the given diagram we get that:


\begin{gathered} P=(-5,-1), \\ Q=(1,-4). \end{gathered}

Therefore:


\begin{gathered} PQ=√((-5-1)^2+(-1-(-4))^2)=√((-6)^2+(3)^2) \\ √(36+9)=√(45)\approx6.71. \end{gathered}

Answer:


6.71.
