Front

How do you find the slope of a line from a graph?

Back

The slope is calculated as the rise over run, which is the change in y divided by the change in x between two points on the line.

Front

If a line has a slope of 2, what does this mean?

Back

A slope of 2 means that for every 1 unit increase in x, the value of y increases by 2 units.

Front

What is the significance of a positive slope?

Back

A positive slope indicates that the line rises as it moves from left to right on the graph.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.
