Types of slope

Front

What is a positive slope?

Back

A positive slope means that as you move from left to right on a graph, the line rises. It indicates a direct relationship between the two variables.

What is a negative slope?

Back

A negative slope means that as you move from left to right on a graph, the line falls. It indicates an inverse relationship between the two variables.

Front

What is an undefined slope?

Back

An undefined slope occurs when a line is vertical. This means there is no change in the x-value, and the slope cannot be calculated.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change between two variables. It shows how much one variable changes in relation to another.

Front

What is the formula for calculating slope?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What does a slope of zero mean?

Back

A slope of zero means that the line is horizontal. This indicates that there is no change in the y-value as the x-value changes.

Front

Can a slope be a fraction?

Back

Yes, a slope can be a fraction, indicating that for every unit increase in the x-direction, the y-direction increases or decreases by a fraction of that amount.
