Write an equation for the line described. give your answer in standard form

You get negative nine over So I could write, oh I'll just write that as 4. We've also seen that you can also express things in point-slope form. So if nine times X is 72, 72 divided by nine is eight. Let me. But the x-intercept isn't as obvious.

And just with these two points, two points are enough to graph a line, we can now graph it.

slope intercept form

Let me see if I can Is it positive? Well, we said X equals zero, this disappears. And to go from zero to 4. Or, what I typically do if I'm looking for the slope, I actually might put this into, into one of the other forms. This is point-slope form and we do videos on that. So once again, that was pretty easy to figure out.
