What is the rate of change in a linear function?

Back

The rate of change in a linear function is the slope, which represents the change in the y-value for a unit change in the x-value.

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal, meaning there is no change in y as x changes.

What is the rate of change of a function represented by a table of values?

Back

The rate of change can be calculated by finding the difference in y-values divided by the difference in x-values for any two points.

What is the significance of a non-constant slope in a function?

Back

A non-constant slope indicates that the function is non-linear, meaning the rate of change varies.

How can you interpret the rate of change in a real-world context?

Back

The rate of change can represent speed, cost per item, or any other quantity that changes with respect to another.

If a line has a slope of 11/2, what does this mean?

Back

This means that for every 2 units increase in x, y increases by 11 units.
