Simple plug in 3 values for x
Pick: 0, 1, 2
OpenStudy (anonymous):
Once you have done that plug and find out what Y is
OpenStudy (anonymous):

i need help
OpenStudy (anonymous):
I'm telling you to replace x with zero. Write down what you already wrote but instead of X put a zero.
OpenStudy (anonymous):
i did
OpenStudy (anonymous):
Can you write it down?
OpenStudy (anonymous):
\[x=0\]

y = –2*x
y = –2*0
What's 0 times -2?
OpenStudy (anonymous):
-2
OpenStudy (anonymous):

Yes so when x=0 the solution is 0
now try with x=1

OpenStudy (anonymous):
ok when x= 1 for y = –2*x you get
y = –2*1
What is -2 times 1
OpenStudy (anonymous):
-2
OpenStudy (anonymous):
Yes so when x= 1 the solution is -2
Now try x=2 ( This is the last one!!!)

idk
OpenStudy (anonymous):
idk that 1
OpenStudy (anonymous):
X= 2
y = –2*x
y = –2*2
What is -2 times 2?

(0, 0), (3, –8), (–2, –4)
(1, –2), (0, 0), (–1, 1)
(–2, 4), (1, –2), (0, 0)
(–2, 4), (1, –2), (2, –3)

You have done two already and from the looks of it seems like the answer should be the second one. Good Job!!
