anonymous · Answer

no pythagoras here, then are on the same horizontal line

anonymous · Answer

from minus two to four is six units to the right

anonymous · Answer

i dont very much like using a triangle to do it , if you can explain more on how to subtract the actual number's there  (-2,-3) and (4,-3) that would be great! because i am still extreamly confused :l

anonymous · Answer

you did not go up or down at all right?  because both $y$ coordinates are $-3$

anonymous · Answer

in other words it is the same as going six blocks east, from -2 to 4
