Types of Slope

Front

What is a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, resulting in an upward trend on a graph.

Front

What is a negative slope?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, resulting in a downward trend on a graph.

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, resulting in a horizontal line.

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 can vary.

Front

How do you identify a positive slope on a graph?

Back

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

Front

How do you identify a negative slope on a graph?

Back

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

Front

What is the equation of a vertical line?

Back

The equation of a vertical line is in the form x = a, where 'a' is a constant.

Front

What is the equation of a horizontal line?

Back

The equation of a horizontal line is in the form y = b, where 'b' is a constant.

Front

What type of slope does the line x = -2 have?

Back

The line x = -2 has an undefined slope.

Front

What type of slope does the line y = 3 have?

Back

The line y = 3 has a zero slope.
