Types of slope

A slope is a measure of how steep a line is on a graph, indicating the rate of change between two points.

A positive slope indicates that as one variable increases, the other variable also increases.

A negative slope indicates that as one variable increases, the other variable decreases.

An undefined slope occurs when a line is vertical, meaning it goes straight up and down, and cannot be expressed as a ratio.

There are three main types of slopes: positive, negative, and undefined.

The slope of a horizontal line is 0, indicating no change in the vertical direction as the horizontal direction changes.

A positive slope can be identified by a line that rises from left to right.

A negative slope can be identified by a line that falls from left to right.

The formula for calculating slope (m) is m = (change in y) / (change in x).

A slope of 1 means that for every unit increase in x, y increases by the same amount, creating a 45-degree angle with the axes.
