    Yes, they never intersect, and what does it matematically mean?

    You have the equation of a line, which is usually given in the general form Ax+By+c=0

    \[Slope=m=\frac{ -coefficient \ of \ x }{ coefficient \ of \ y }\]

    in your case, you have it put in a different way, with the y solved, that's what we call the explicit form of the equation of the line

    and so, to calculate the slope DIRECTLY just by seeing the equation, we have a trick

    IF they give you the equation in the general form, Ax+By+c = 0, the slope is -A/B

    Now, if you have it in the explicit form, y=mx+n, what would be the slope in there? try it

    Thanks, I know what you mean, but the ammount of concepts that one needs to DOMINATE to really know math is so big that sometimes i just can't explain something in 2 words

    Well,giving direct answers or providing the whole solution is not allowed on OS @GCR92 We do not want the answerers to do all the work,we would like the asker to participate in the solution though :)
