x + 4y = 12

We can't draw graphs on this forum. Sorry.

however, since the equation is that of a straight line, just pick two points that satisfy the equation, and draw a line between them.
Which two? Doesn't matter, but the easiest ones to calculate are when x=0 or y=0.
So, since (0,3) and (12,0) lie on the line, plot them and draw the line.
