How do I find the distance between (-9,3) and (-1,-5)

By using the Pythagorean theorem. The line between the two points is the hypotenuse of a triangle with perpendicular side lengths of 8 in the x direction and 8 in the y direction. The 8's come from the differences in x and y coordinates of the two points.

Plotting the points on a graph should be helpful to you for visualizing what is going on.

So Distance = sqrt[(8)^2 + (8)^2]
That can be reduced to 8 sqrt 2
