Egypt, for 30 years, had been in a downhill going into a downhill.

Slanting downhill, but walkable.

You can't slide off downhill.

And we've been going steadily downhill.

If you look at the scene, Egypt, for 30 years, had been in a downhill going into a downhill.

We don't know how they could measure so accurately so that the water kept moving gently downhill but relentlessly downhill.

And it doesn't take long to go downhill.

Only thing good about it is it's downhill.

Yeah, Mr. Moran, if this continues to go downhill,

Any place headed downhill is always depressing like this.

From that point on, everything else was pretty much downhill.

Just a little more of this, then easy downhill going.

Just a little more of this, then easy downhill going.

Follow me downhill and we'll go up the next gully.

So the slope of the slope.

That's the slope of the slope, or the rate of change of the slope itself.

It's downhill from now on. I wanted to thank Emeka and Chris.

If you do that, the rest is just pretty much a coast downhill.

The red line is way downhill, the blue line is a good line.

Slope Map

Low slope

High slope

Slope decreases.

Slope... arms!

Zero is a higher slope than some negative slope here.

So they're telling us the slope, slope of negative 1.

The slope would be a negative slope, and here it's a positive slope, but if we took a point here, the slope would be even more positive.

Your slope over here is the slope of the tangent line.

It'll have slope.

The tangent slope.

Slope is decreasing.

What's the slope?

So this is in neither point slope nor in slope intercept form.

And which of these has a positive slope, positive slope of 2?

So line A, the slope is pretty easy to figure out, it's already in slope intercept form, its slope is 3.

I don't need much to do my best... And if by chance things go downhill...

Slope AB, or we could say slope BC, should be equal to the negative inverse of the slope of A to B.

AB, you get slope AB times slope BC is equal to negative 1.

You can see here the slope is downward because the slope is negative.
