Question 58912
The distance between two points (x1, y1) and (x2,y2) is sqrt{(x2-x1)^2+(y2-y1)^2}

So distance between (-4,0) and (-5,-3) = sqrt{ (-5+4)^2 + (-3-0)^2 }
                                       = sqrt{ (-1)^2 + (-3)^2}
                                       = sqrt{ 1+9 }
                                       = sqrt(10)
                                       = 3.16
