I think I'm correct, but I still want someone to double check my answer

if y=2x then the y for -1 would be -2
so your first coordinates are )-1, -2) and so on so forth
second coordinates are (0,0) third are (1,2) fourth are (3,6) fifth are (4,8)
not sure if that's what you had or not but that should be about right.
