@zepdrix could you help me again plz

4. zepdrix

Do you understand how to draw it? c: I think that was helpful last time.

5. Ashely14

it was verry helpful last time but i dont know how to draw it

Our coordinates move like this: $$\large\rm (right/left,\quad up/down)$$ If the first number is positive, we move to the right. If it's negative, we move to the left. If the second number is positive, we move up. If it's negative, we move down.

7. Ashely14

ok

8. zepdrix

So for the first coordinate $$\rm (-3,-3)\quad=\quad (\leftarrow3, \downarrow3)$$

9. zepdrix

|dw:1442537386997:dw|

10. zepdrix

|dw:1442537469739:dw|So there's our first point.

11. Ashely14

k

12. zepdrix

|dw:1442537531996:dw|The next coordinate $$\rm (7,-3)$$ is telling me to go $$\rm (\rightarrow7, \downarrow3)$$

13. zepdrix

How bout the third point, where we going to put that one? :)

14. Ashely14

|dw:1442537791893:dw|

15. zepdrix

Ah very close! :) (7,2) means we move right 7 and 2 up.

16. zepdrix

oh you put 2 dots lol

17. Ashely14

xD

18. zepdrix

|dw:1442537898080:dw|

19. zepdrix

|dw:1442537939625:dw|So that's telling us that our last point should be located somewhere around here, ya?

20. zepdrix

So which option makes the most sense?

21. Ashely14

D.

22. zepdrix

yay good job \c:/

23. Ashely14

thanks @zepdrix
