Usage

What does slope mean? In mathematics, the slope (also called the gradient) of a line is a measurement of how steep the line is or how much of a slant it has. In math, a line is an object with no thickness that extends forever in both directions. In basic math, we assume lines to be perfectly straight, meaning they don’t curve or change directions to form angles. Take a piece of graph paper to create a Cartesian plane by drawing two perpendicular lines. These two lines are called the axes. The axis going sideways is the x-axis, and the axis going up and down is the y-axis. We use these axes to label where any point on the plane is located. You can then measure the slope of a line compared to the x-axis by using the Cartesian coordinates on your Cartesian plane.

Synonym Usage

Slope, slant mean to incline away from a relatively straight surface or line used as a reference. To slope is to incline vertically in an oblique direction: The ground slopes ( upward or downward ) sharply here. To slant is to fall to one side, to lie obliquely to some line whether horizontal or perpendicular: The road slants off to the right.

Etymology

Origin of slope

First recorded in 1495–1505; aphetic variant of aslope; akin to slip ¹

Explanation

If you find yourself on a slippery slope, watch out: you could be sliding down a hill. Land that is not level is called a slope. Slope can also be a verb, as in land that slopes down to sea level. Language experts believe the word slope came from the Middle English word aslope, an adverb that means “at an angle.” The word has a noun form you can use for something that is at an angle — on a slope — like a steep hill or the ramp in a parking garage. It also has a verb form that can be used to describe something that slants, like someone's signature with letters that slope to the left or an angled haircut that slopes to cover one eye.
