What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how steep the line is and the direction it goes (positive or negative).

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

Front

What type of slope does a line with a positive slope have?

Back

A line with a positive slope rises from left to right, indicating that as the x-value increases, the y-value also increases.

Front

What type of slope does a line with a negative slope have?

Back

A line with a negative slope falls from left to right, indicating that as the x-value increases, the y-value decreases.

Front

What does a slope of zero indicate?

Back

A slope of zero indicates a horizontal line, meaning there is no change in the y-value as the x-value changes.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, meaning the x-value does not change while the y-value can vary.
