For parallel lines:
"All parallel lines have the same slope!"

For perpendicular lines:
"Their slopes' product is -1"

poto · Answer

Okay so -2x+3y=11 shouldn't be in parallel

3mar · Answer

Why "shouldn't"??
Is its slope is equal to the slope of the line (-2x+3y=12)??

poto · Answer

Can you look at this to see, http://prntscr.com/d7qqz4

3mar · Answer

Yes, I saw.
Are they parallel or not?

poto · Answer

They look parallel. :)

3mar · Answer

They are already parallel, even without graphing because their slopes are the same (2/3)

so next?

poto · Answer

Yes 3x+2y=-2 is perpindicular.

3mar · Answer

You hit the right target!

poto · Answer

Yes! and for the next one, -2x+y=12 is neither.

3mar · Answer

Congratulations! 
I think you got it 100% correct!
