How do you identify the slope from a graph?

Back

The slope of a line can be identified by calculating the rise over run, which is the change in y divided by the change in x between two points on the line.

Front

What is the significance of a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.
