Week 15 – Slope

The slope of a line segment is the steepness of the line. It is the ratio of the rise (vertical) over the run (horizontal).

Horizontal lines have a slope of 0, and vertical lines have an undefined slope.

In math, slope is represented by the letter m.

Slope Formula: The slope of a line can be determined even without the graph as long as you have the two points and the slope formula. The formula is as follows:

M= \frac{y2-y1}{x2-x1}

Example: Determining the slope of points A (4,5) and B (2,1)
