slope = m =

Slope

The slope of a line is the ratio of the vertical change to the horizontal change between any two points on the line.

As a formula,

Here, (x1, y1) and (x2, y2) are two points on the line.

Find the slope of the line that contains the points (- 5, 3) and (4, 0).

Here, x1 = - 5, y1 = 3, x2 = 4, and y2 = 0.

means the line falls1 unit (because of the negative) for every three units to the right as shown by the red arrows on the graph.

Geometric Interpretation of slope:

Find the slope of the line that contains the points (- 1, 3) and (- 1, - 2).

which is undefined.

In example two, the slope was found to be undefined. Here the two points lie on a vertical line.

The slope of a vertical line is undefined.

The slope of a horizontal line is zero.
