This is going to be a lot like what we just did at the end of the last section.
So far, I've shown you how to find the slope from the graph and when you have two points...
But, what if you just have the equation?
If it's like this guy, then it's a snap!
So, what if it's in standard form like this?
Well, it's not too bad. We
just do a little algebra and get it into
y = mx + b form.
To do this, we solve for y:
Find the slope using algebra:
