Graphing linear equations is easier when the equations are put into the slope-intercept form y = mx+b:
2x-3y+=+-6 Add 3y to both sides.
2x+=+3y-6 Add 6 to both sides.
2x%2B6+=+3y Divide both sides by 3.
%282%2F3%29x+%2B+2+=+y or y+=+%282%2F3%29x+%2B+2
2x-y+=+2 Add y to both sides.
2x+=+y%2B2 Subtract 2 from both sides.
2x-2+=+y or y+=+2x-2
