Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x. A positive slope indicates an increasing line, while a negative slope indicates a decreasing line.

If a linear function has a slope of -1, what does this indicate about the line?

Back

A slope of -1 indicates that for every unit increase in x, y decreases by 1 unit, resulting in a downward sloping line.

Front

How do you determine the rate of change from a table of values?

Back

The rate of change can be found by calculating the difference in y-values divided by the difference in x-values between two points.

In the context of a cost function, what does the fixed cost represent?

Back

The fixed cost is the initial cost that does not change with the number of items purchased, such as a membership fee.
