Front

What is the definition of slope?

Back

Slope is defined as the ratio of vertical change (rise) to horizontal change (run), or Rise/Run.

How do you find the slope using slope triangles?

Back

To find the slope using slope triangles, create a right triangle where the vertical leg represents the rise and the horizontal leg represents the run. The slope is the rise divided by the run.

What does a slope of 0 indicate?

Back

A slope of 0 indicates a horizontal line, meaning there is no vertical change as you move along the line.

How can you determine the slope from a graph?

Back

You can determine the slope from a graph by selecting two points on the line, calculating the rise and run between them, and then dividing the rise by the run.

What is the formula for slope?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.
