how can i know wheter the graph of the following equation is parallel, perpendicular, or neither. thank you.
-------------
If the slopes are the same, the lines are parallel.
If the product of the slopes is -1, the lines are perpendicular.
2x+3y=4
y=(-2/3)x+(4/3)
slope = -2/3
-------------------
3x+2y=6
y=(-3/2)x+3
slope = -3/2
------------------
Slopes are not equal and their product is not -1 so the lines are
neither parallel nor perpendicular.
-------------------
