Write x= -2 in standard form using only integers and a positive coefficient for x?

Ok so I have two points (-2,2) and (-2,0) so the slope is undefined and the only equation I have is X= -2 but i have to make into standard form with a positive coefficient for x. choices for answers are:
a) x+3y= 6
b) x-3y= 2
c) -x+3y= -6
d) x-3y= 6

please help, ive tried solving for x to get -2 and using the coordinates also but nothing works!

Additional Details

technically its a two part question, in the first one it gave me the points (-2,0) and (-2,2) and asked for the slope which came to 2/0 or undefined since you cant divide by 0. the second problem is exactly worded:

Write the equation in standard form using only integers and a postive coefficient for x.

Hmm... I tried all the answers also and none are working for me which is why I decided to ask on here. Ive triple checked everything as far as points, answers, etc. and so far have found no mistakes. Im so confused.

hey im in high school but ill help.

choice c is eliminated because the coeffecient of x is negative

plug in point (-2,0)

a= -2+ 3(0) = 6. false

b= -2 + 3(0)=2 false

d=-2-3(0) =6 false.
ummmm

The equation of the line thru the points (-2,2) and (-2,0) is:
x = -2

This equation simply does NOT have a "y" in it.

None of the choices are right. They don't make any sense. Are you sure you wrote the question down correctly?

And as you noted, the slope is undefined.
