And this is one predictor. So, here are the coefficients that go into this equation.

And you can see they graphed that.

This could be a oneway trip.

So let's graph this purple equation here.

It's the exact same function.

What about this line?

We could say now that y is equal to f inverse of x.

What might they find?

So 1, 2, 3.

And how I set about that, I got some splinters of wood.

Let me see what it says.

It's going to look something like this.

There's an implicit 1 multiplying times this b.

Well, we can do the same thing.

So that works.

So those are the two 0's that they've given us.

Elysium was a oneway ticket.

And this is already in mx plus b form, or slope intercept form.

Slope of negative 1, that's what's multiplying the independent variable, and then you have a y intercept of 50, or maybe we should say an a intercept.

We'll have to do some research on that. b is the y intercept and the y intercept is just where does it intersect the y axis.

Where this 'm' right over here, that is the slope of the line, and this

And they graphed that here.

So, let's see. y equals x squared minus 4.

Problem 23.

We're all on oneway trips.

Once again, this is the x axis, and this is the f of x axis.

Mr. Gus Priamos.

So that's plus eight three.

And our algebra confirms our drawing.

Now, let's graph it.

Here, when x is 0, y is negative 1.

So the y intercept is easy to eyeball.

So that's why the slope is negative one three.

So this would be x is equal to minus 1 4.

The y intercept just tells us where we intercept the y axis.

All right. See, so I was actually wrong.

Find the equation for the blue line?

So in this situation, this point is on both lines.

Now let's look at the graph and see if that makes sense.

So that's the x intercept.

It's only seven miles, but only two people have been there, 49 years ago.

So the slope is 2.

OK, I'll paste it there.

They say that we have 0's at the point minus 1, 0 and the point 2 comma 0.

The mayor screened his eyes with his hand.
