Answer:
X = -2 - y/3
Step-by-step explanation:
First you need to know the current equation, for that:
Notice that when Y = 0, X = 2.
When Y = 6, X = 0
Therefore the equation is X = 
To move that to the left of the X axis (negative direction) you just have to reduce the X number:

Proof is something like I have proof of u eating pie. I think it might be D.
Answer:
