In the xy-plane, what is the slope of line l? (1)Line l dose not intersect the line with equation y = 1 - x. (2)Line l intersects the line with equation y = x - 1. 选项: 答案: A
In the xy-coordinate plane, the slope of line ℓ is . Does line ℓ pass through the point ? (1) Line ℓ passes through the point (4,4). (2) Line ℓ passes through the point (–4,–2). 选项: A、Statement (1) ALONE is sufficient, but statement (2) alone is not suffici...
In calculus, the slope of a line, also known as the gradient is important to calculate because it explains how steep the line is. If we have an equation of a line in the formy=mx+c, the slope of this line is calculated asΔyΔx=m. ...
Every point has a set of coordinates: an x-value and a y-value, written as an ordered pair (x, y). The x value tells you where a point is horizontally. The y value tells you where the point is vertically.Consider two points on a line—Point 1 and Point 2. Point 1 has ...

The slope of a line through two points (x1,y1) and (x2,y2) is the ratio of the change in the y-coordinates to the change in the x-coordinates: y2−y1x2−x1. The phrase rise over run is often used to describe slope, reflecting the common interpretation of the y-coordinate as...
