Answer:
X = -2 - y/3
Step-by-step explanation:

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:

An equilateral triangle cross section can be obtained by cutting the cube by a plane defined by the midpoints of the three edges emanating from any one vertex.
