* The vertical distance between two points on your property
* The horizontal distance between the same two points
Once you have this information, you can use the following formula to calculate the slope:
```
slope = vertical distance / horizontal distance
```
For example, if the vertical distance between two points on your property is 10 feet and the horizontal distance between the same two points is 100 feet, then the slope of your property is 0.1 (or 10/100).
The slope of your property is expressed as a percentage or a ratio. For example, a slope of 0.1 can also be expressed as 10% or 1:10.
The slope of your property is an important factor to consider when designing your landscape, as it can affect drainage, erosion, and the stability of your soil.
