Answer 2

Well for Part 1 you could just shift all the coordinates by the same amount in some direction...

Answer 3

I don't get how to do that.

Answer 4

ie if, for example, you upped the x cordinates by 1. you shift the whole thing 1 unit to the right (try it)

Answer 5

So, in stead of -7,3 it would be -6,2?

Answer 6

-7,2*

Answer 7

3* AH!
i got it.

Answer 8

:-)

Answer 9

So it would be for part 1
A-(-7,3)
B-(-5,8)
C-(1,2)
D-(-1,2)
?

Answer 10

I'll take your word for it, I haven't looked...

Answer 11

lol and part 2?

Answer 12

Double the lengths, maybe...?

Answer 13

lol alright

Answer 14

Seems like you are getting the hang of it OK.
