Answer:

Distance(PQ)=\sqrt{113}

Step-by-step explanation:

In coordinate geometry distance between the two points can be find by using the distance formula:

For two points :

            (x_1,y_1)\\and \\(x_2,y_2)

Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

For points: P(3,-1) and Q(-5,6)

Distance (PQ):

                    =\sqrt{(-5-3)^2+(6-(-1))^2} \\\\=\sqrt{(-8)^2+(6+1)^2}\\\\ =\sqrt{(-8)^2+(7)^2} \\\\=\sqrt{64+49}\\\\Distance(PQ) =\sqrt{113}\\\\
