What is the slope of a line?

Back

The slope of a line measures its steepness and direction. It is calculated as the change in y divided by the change in x (rise over run). A positive slope indicates an increasing function, while a negative slope indicates a decreasing function.

Front

What does a positive slope indicate about a function?

Back

A positive slope indicates that the function is increasing; as the x-values increase, the y-values also increase.

Front

What does a negative slope indicate about a function?

Back

A negative slope indicates that the function is decreasing; as the x-values increase, the y-values decrease.

How can you determine the rate of change from a graph?

Back

The rate of change can be determined by calculating the slope of the line on the graph. It is the ratio of the vertical change to the horizontal change.

What is the difference between a linear and a nonlinear graph?

Back

A linear graph forms a straight line, while a nonlinear graph can be curved or have varying slopes.
