What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the function. It indicates how much the y-value changes for a one-unit increase in the x-value.

What does it mean if a linear function has a positive slope?

Back

If a linear function has a positive slope, it means that as the x-value increases, the y-value also increases, indicating a direct relationship.

Front

What does it mean if a linear function has a negative slope?

Back

If a linear function has a negative slope, it means that as the x-value increases, the y-value decreases, indicating an inverse relationship.

How can you determine if a point lies on the graph of a linear function?

Back

To determine if a point (x, y) lies on the graph of a linear function, substitute the x-value into the function's equation and check if the resulting y-value matches.
