Answer:
1. No
2. No
3. No
4. No
Explanation:
y=2 so you multiply your x by 2 and you should come out with your y
your y should be 1 * 2 = 2 but is 9 ---->for (1, 9)
your y should be -6 * 2 = -12 but is 2 ---->for (-6, 2)
your y should be 2 * 2 = 4 but is -8 ----->for (2, -8)
your y should be 0 * 2 = 0 but is -4 ----> ( 0, -4)
side note -I'm sorry if you get it wrong,hopefully it's right though.
