Please see below.

Explanation:

It is a linear equation, so it may be appropriate and sufficient to the graphselect three points wide apart to draw the graph.

Let x=0x=0, then we have 0-6y=1206y=12 or y=12/(-6)=-2y=126=2 and hence our first point is A(0,-2)A(0,2).

Next let y=0y=0, then we have 2x-0=122x0=12 or x=12/2=6x=122=6 and hence our second point is B(6,0)B(6,0).

Let us select another point with x=-6x=6, then we have 2xx(-6)-6y=122×(6)6y=12 or -12-6y=12126y=12 or 6y=-246y=24 or y=24/(-6)=-4y=246=4 and our tird point is C(-6,-4)C(6,4).

Table could be

Tablecolor(white)(XXXXX)xcolor(white)(XXXXX)yXXXXXxXXXXXy

Acolor(white)(XXXXXXX)0color(white)(XXXX)-2XXXXXXX0XXXX2

Bcolor(white)(XXXXXXX)6color(white)(XXXXX)0XXXXXXX6XXXXX0

Acolor(white)(XXXXXX)-6color(white)(XXXX)-4XXXXXX6XXXX4

Now just join points to get the graph, which appears as below.
graph{2x-6y=12 [-9.75, 10.25, -7.44, 2.56]}
