Question 87879: This is my first time on this site and the problem looks easy but I am really
having the blues. Graph y=3x=4 and y=-1/3x-4 determine whether the two lines
are parallel,perpendicular ot neither.The teacher taught it this way but I am
still having a hard time with it.

You can put this solution on YOUR website!
I assume that there is a typo in the first equation since you have written:
y=3x=4 and it most likely should be:
y+=+3x%2B4 (Red line on the graph)
The second equation is:
y+=+-%281%2F3%29x-4 (Green line on the graph)
Graph these two equations.

You can determine the answers from the graph.
