Slope & Slope-Intercept

Front

What is the definition of slope?

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the rise (vertical change) to the run (horizontal change) between two points on the line.

How do you calculate the slope using rise/run?

Back

To calculate the slope using rise/run, divide the change in y (rise) by the change in x (run) between two points on the line.

Front

Write the slope-intercept form of a line with slope -1/2 that passes through the point (-2, 4).

Back

The equation is y = -\frac{1}{2}x + 3.

Front

If a line has a slope of 3, what does this indicate about its steepness?

Back

A slope of 3 indicates that for every 1 unit the line runs horizontally, it rises 3 units vertically, making it quite steep.
