describes the direction and steepness of a line.

Slope:

​

​In general , slope is the ratio of vertical change to horizontal change.

We often think of this as "rise over run" or "change in y over change in x"​

​y_2-y₁

​x_2-x₁​

​

​*if a slope doesn't simplify to a whole number, we leave it as a fraction! This is so we can easily identify the relationship! (the rise AND the run)

​Table

You can also use two points to find slope, simply by finding the change in y-values and x-values, respectively. Finding the slope is even easier if the points are presented as a graph. We can identify the two points and count the rise/run units

​Graph

The equation of a line can be written in different forms. The equation shown above is slope-intercept form. This equation is written in terms of y, the coefficient of x is the slope (denoted by m) and the constant (denoted by b) is the y-intercept (where the line crosses the y-axis.

​Identifying slope with...

Slope can be identified using a table by finding the

change in y-values and change in x-values.
