Homework Help: pre-calc

Posted by britteny on Wednesday, January 10, 2007 at 7:01pm.

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.
