Key Differences

An incline is generally understood as any surface that tilts upwards or downwards, allowing for movement from one elevation to another. Slope, on the other hand, specifically quantifies this tilt, typically in terms of the vertical change per unit of horizontal distance.
Inclines can be natural, like a hillside, or man-made, such as a ramp. Slopes are crucial in various fields, including engineering and geography, to describe how steep a particular incline is.
The term incline often implies usability, such as paths, roads, or ramps designed for traffic or pedestrians. Slope is more technical, used in contexts requiring precise calculations, like in construction or land surveying.
In everyday language, people may use "incline" to describe a slight rise that is easy to navigate. Whereas "slope" might be used to discuss steeper, more challenging gradients.
In physical fitness, an incline is used to describe surfaces or machinery designed to simulate uphill movements, enhancing intensity. Slopes are crucial in sports such as skiing, where the angle of the slope affects the speed and difficulty of descents.

Slope

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Todhunter (1888) who wrote it as "y = mx + c".Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.
