Sloping refers to a surface or line that is not flat but instead inclines at an angle. This can be seen in various contexts, such as in geography where hills and mountains have sloped terrains, or in architecture where roofs may have a sloped design to allow for water drainage. In mathematics, sloping is often described using the concept of a slope, which measures the steepness of a line on a graph. The slope is calculated as the change in vertical distance divided by the change in horizontal distance, helping to understand relationships between variables, such as in the case of linear equations.
