The distance formula is  √ (x2  - x1)2 + (y2  - y1)2      It does not matter which point is designated (x1,y1) and which is                                                                                   (x2,y2), so long as you keep the x's and y's straight.
  √ (-5 -3)2   + ( 6 - 0)2
                                                                                
  √  (-8)2   + (6)2       =   √  64  +  36     =   √  100          =  10
 
The length of the line is 10.
