Which subject would typically include the concept of "slope"?

The concept of "slope" is fundamentally a mathematical concept that measures the steepness or incline of a line in a graph. In mathematical terms, slope is defined as the ratio of the vertical change (rise) to the horizontal change (run) between two points on a line. This concept is crucial in various areas of mathematics, particularly in algebra and geometry, where it is used to understand linear functions and their graphs.

In applications beyond pure mathematics, such as physics (a branch of science), slope can also denote rates of change or describe relationships between quantities. However, it is primarily in mathematics that slope is taught explicitly and with a focus on graphical representations and equations. Therefore, mathematics is the subject where the concept of slope is most prominently featured and universally understood in its foundational context.
