To convert an angle of 18 degrees into rise over run, you can use the tangent function, which is the ratio of the rise (opposite side) to the run (adjacent side) in a right triangle. The tangent of 18 degrees is approximately 0.3249. Therefore, for every 1 unit of run, the rise would be about 0.3249 units, giving a rise over run ratio of approximately 0.325:1.
Rise over run
rise/run = tangent 15 degrees rise = tan(15) x 48 = 12.86 inches
45 degrees.
Rise over run gives you slope, not points
Slope equals rise over run.
If you're talking about slope, it is rise over run. But why is it not the other way run over rise?
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)
Rise over run
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/run = tangent 15 degrees rise = tan(15) x 48 = 12.86 inches
45 degrees.
a run in math is referring to slope, which is rise over run. rise is how far you travel up, and run is how far you travel over.
Rise over run gives you slope, not points
Slope equals rise over run.
To express .25 inch per foot as a percent slope multiply rise over run times 100. This can be expressed rise/run x 100. rise=.25 inch run=12inches. So .25 divided by 12 times 100 equals 2.083 which can be rounded to 2.1 or simply 2% slope

It could have been either but it must have been easier to put the y-coordinate on top.
