How do you calculate the rate of change between two points?

Back

To calculate the rate of change (slope) between two points (x1, y1) and (x2, y2), use the formula: (y2 - y1) / (x2 - x1).

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

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

Back

A slope of 0 means that the line is horizontal, indicating no change in the y-value as the x-value changes.

If a line has an undefined slope, what does that mean?

Back

An undefined slope occurs when a line is vertical, indicating that the x-value does not change while the y-value changes.

What is the formula for finding the slope of a line given two points?

Back

The formula for finding the slope (m) of a line given two points (x1, y1) and (x2, y2) is: m = (y2 - y1) / (x2 - x1).
