About Slope

Slope tells us how steep a line is. It is calculated as the change in y divided by the change in x. A positive slope means the line is increasing, while a negative slope means it's decreasing.

Examples of Different Slopes

Positive Slope

Line rises from left to right (e.g., m = 2)

Negative Slope

Line falls from left to right (e.g., m = -1.5)

Zero Slope

Horizontal line (e.g., m = 0)

Undefined Slope

Vertical line (e.g., x = constant)
