When you blow - you're moving the air that was static over the top of the paper. This lowers the air pressure relative to the air underneath, so it pushes upwards on the piece of paper.
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?
He wanted to see them rise.
Tissue paper is not very dense. I assume it is one piece and is on a flat surface. When blowing down straight and in the middle, air is able to move through the tissue paper because it is porous. You keep forcing air down and the molecules are bombarding each other and when completely through the tissue paper the fastest way to escape and allow the other molecules through is by escaping under the tissue paper and outwards. This is what lifts the tissue paper.
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.

The slope can be remembered as "rise over run". When the slope is an integer, it means that the rise over run is positive.
rise divided by run: a fraction, rise is y and run is x (you run on a horizontal plane) (you rise on a vertical plane)
