Types of Slopes

Front

What is a positive slope?

Back

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

Front

What is a negative slope?

Back

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

Front

What is a zero slope?

Back

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

Front

What is an undefined slope?

Back

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

Front

How can you identify a positive slope on a graph?

Back

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

Front

How can you identify a negative slope on a graph?

Back

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

Front

What does a horizontal line represent in terms of slope?

Back

A horizontal line represents a zero slope.

Front

What does a vertical line represent in terms of slope?

Back

A vertical line represents an undefined slope.

Front

If the equation of a line is y = 2x + 3, what type of slope does it have?

Back

The slope is positive (2).

Front

If the equation of a line is y = -3x + 1, what type of slope does it have?

Back

The slope is negative (-3).
