Math: Slope

What do you think slope is?

What is really slope?

What is slope? If you have ever walked up or down a hill, then you have already experienced a real life example of slope

As you go up hill, you may feel like you are spending lots of energy to get yourself to move.

The steeper the hill, the harder it is for you to keep yourself moving

Keeping this fact in mind, by definition, the slope is the measure of the steepness of a line.

In real life, we see slope in any direction. However, in math, slope is defined from left to right.

I repeat we always measure slope going from left to right. This is very important!

There are three types of slope you can encounter. A slope can be positive, negative, or equal to zero. When the slope is equal to zero, we say that there is no slope

Positive Slope

If you go from left to right and you go up, it is a positive slope

Name some types of positive slopes?

Negative Slope

If you go from left to right and you go down, it it a negative slope

Name types of negative slopes?

Zero Slope

If you go from left to right and you don't go up or down, it it a zero slope

Name types of zero slopes?

Slope=Rise and Run

That steepness can be measured with the following formula:

-up

DODJDJ-down

How do you know the slope direction?

The slope going up is positive and the slope going down is negative

But the slope going even is zero

And the slope going vertical is undefined
