determine if the following lines are parallel, perpendicular or neither. Explain your reasoning.
-2x+3y=3 2x+3y=3
Rewrite them in y = mx + b form to get the slopes, m.
The lines are parallel of the slopes are the same. They are perpendicular if the product of the slopes is -1
I FOUND THAT Y=2X/3+1 AND Y=-2X/3+1
ARE THEY PERPENDICULAR, RIGHT???????
No, they aren't . The product of the slopes is not -1. It is -4/9 in this case
SO WHAT IS IT???????????????????????
Neither.
