Slope equals rise over run.
Rise over run
Rise over run gives you slope, not points
It could have been either but it must have been easier to put the y-coordinate on top.
The measure of the steepness of line expressed as rise over run is called slope.
When you blow on the top of a piece of paper, the air you blow creates a region of low pressure above the paper. This low-pressure area draws the paper upwards, causing it to rise. Additionally, the fast-moving air you blow creates momentum that lifts the paper.
When you blow over a strip of paper, the faster-moving air above the paper creates lower pressure than the air below it. This pressure difference causes the paper to rise towards the area of low pressure, demonstrating Bernoulli's principle, which states that as the speed of a fluid (or air) increases, its pressure decreases.
When you blow air above a sheet of paper, you create a region of low pressure due to the fast-moving air. This lower pressure above the paper creates a pressure difference between the top and bottom of the paper, causing the paper to be pushed upwards by the higher air pressure below it. This lift force causes the paper to rise.

If you're talking about slope, it is rise over run. But why is it not the other way run over rise?
When you blow air above the tissue paper, you create an area of low pressure above the paper due to the Bernoulli principle. This causes the higher air pressure below the tissue paper to push it upward, resulting in the tissue paper rising.
When you hold a spiral paper over a lit candle, the heat causes the air within the spiral to rise, creating a mini updraft that makes the spiral rotate. The rotation is caused by the temperature difference between the inside and outside of the spiral paper.

Rise over run
Answer To put it simply, by blowing across the piece of paper you are creating low pressure. This is the same way that an airplane wing works. Except on an air craft air is forced underneath the wing to create lox pressure underneath it creating an upwards force called lift which pushes the air craft up. The piece of paper is so light that the low pressure that you are creating over the top of it makes the paper rise toward it. The same thing happens with your shower curtain in the shower sometimes. Did you ever wonder why the shower curtain closes in on you while in the shower? Well now you know. EDIT! - The above answer is the common explanation but it is incorrect. The paper lifts because the airflow sticks to the paper and is directed downward - forcing the paper upward. For the above explanation to be true you should be able to hold a piece of paper horizontally and make it lift by blowing across it - but it doesn't.
The slope can be remembered as "rise over run". When the slope is an integer, it means that the rise over run is positive.
