: My son is working on rise over run and finding the slope of a line. it has been a long time since I have done this kind of Math, he doesn't understand this at all.
Equation: Y<3X - 4
Please explain in steps so that I can explain it fully to him.
Thank you

You can put this solution on YOUR website!
Well, first, the "equation" you have posted is really an "inequality".
If this was just a typo then we'll proceed from there.
You probably meant to write:
y+=+3x-4 instead of y+%3C+3x-4
This equation of a line is written in what is called the "slope-intercept" form y+=+mx%2Bb in which m is the slope and b is the y-intercept.
Compare this with your equation:
y+=+3x-4
y+=+mx%2Bb
You can see that the slope, m, is 3 and the y-intercept is -4
Just by way of explanation, the inequality that you wrote (inadvertently perhaps?) really defines an area rather than a line and the slope of an area is not meaningful, although the slope of the boundary of the area would be meaningful.
