Definitions:

Cartesian Coordinate System

A coordinate system that specifies each point uniquely in a plane by a set of numerical coordinates, which are the distances to the point from two perpendicular directed lines.

Variable

An element, feature, or factor that is likely to vary or change; in scientific experiments, the characteristic that is tested to observe its effects.

Time

A measurable period during which events occur, processes take place, or conditions exist.

Slope

In mathematics and economics, it's the measure of the steepness or incline, often used to describe a change in a variable in relation to a change in another variable.
