A1 3.1 Horizontal and Vertical lines

Front

What is a horizontal line in a graph?

Back

A horizontal line is a straight line that runs parallel to the x-axis. It has a constant y-value for all x-values.

Front

What is a vertical line in a graph?

Back

A vertical line is a straight line that runs parallel to the y-axis. It has a constant x-value for all y-values.

Front

What is the equation of a horizontal line?

Back

The equation of a horizontal line can be expressed as y = k, where k is a constant.

Front

What is the equation of a vertical line?

Back

The equation of a vertical line can be expressed as x = k, where k is a constant.

Front

Which type of line has an undefined slope?

Back

A vertical line has an undefined slope.

Front

Which type of line has a slope of zero?

Back

A horizontal line has a slope of zero.

Front

How do you identify a horizontal line on a graph?

Back

A horizontal line can be identified as a line that does not rise or fall as it moves from left to right.

Front

How do you identify a vertical line on a graph?

Back

A vertical line can be identified as a line that goes straight up and down without moving left or right.

Front

What is the slope of the line represented by the equation y = -2?

Back

The slope is 0, indicating a horizontal line.

Front

What is the slope of the line represented by the equation x = 3?

Back

The slope is undefined, indicating a vertical line.
