What is the significance of a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing a direct relationship.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, showing an inverse relationship.

Front

How can you identify the slope from a graph?

Back

The slope can be identified by calculating the rise over run between two points on the line.

If a line has a slope of 0, what does that mean?

Back

A slope of 0 means the line is horizontal, indicating that the y-value does not change as the x-value changes.

Front

What is the slope of a vertical line?

Back

A vertical line has an undefined slope because the change in x is 0, leading to division by zero.
