You can put this solution on YOUR website! Parallel lines have the same slope
Perpendicular lines have the inverse negative of each other..ie: if slope is
-2 on one line it would be 1/2 the perpendicular or if it was 2 on one line it would be -1/2 in the perpendicular
if you were to rearrange these equation to represent the linear equation, which is y=mx+b with m = slope
2x + 3y = 8 would be 3y = -2x + 8 would be y = -2/3(x) + 8/3
2X + 3Y = 6 would be 3y = -2x + 6 would be y = -2/3(x) + 2
therefore they have the same slope (m) and will be parallel lines.
