Positive, Negative, Zero, or Undefined Slope

Front

What is a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases. It is represented by a line that 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. It is represented by a line that 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. It is represented by 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 does.

Front

Which letter has a positive slope as part of its shape?

Back

The letter 'M' has a positive slope as it rises from left to right.

Front

Which letter has a negative slope as part of its shape?

Back

The letter 'X' has a negative slope as it falls from left to right.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change between the y-value and the x-value.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What type of slope does a horizontal line have?

Back

A horizontal line has a zero slope.

Front

What type of slope does a vertical line have?

Back

A vertical line has an undefined slope.
