Slope from a Graph

Front

What is slope?

Back

Slope is the ratio of rise over run, vertical change over horizontal change, or change in y over change in x.

Front

If a line rises 2 units and runs 1 unit, what is the slope?

Back

2/1

Front

If a line falls 2 units and runs 1 unit, what is the slope?

Back

Front

What does a slope of 1 indicate?

Back

The line rises 1 unit for every 1 unit it runs.

Front

What does a slope of -1 indicate?

Back

The line falls 1 unit for every 1 unit it runs.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope = (y2 - y1) / (x2 - x1).
