Graphing Horizontal and Vertical Lines

The video tutorial explains how to graph equations where x or y is equal to a constant. It demonstrates that when x equals a constant, the graph is a vertical line, and when y equals a constant, the graph is a horizontal line. The tutorial includes examples with x = 3, y = -2, x = -3, and y = 4, and concludes with a review of these graphing concepts.

What type of line is formed when x is equal to a constant?

• Horizontal line

• Vertical line

• Diagonal line

• Curved line

Where would the point (3, 0) be located on the graph of x = 3?

• On the horizontal line at y = 3

• On the vertical line at x = 3

• On the y-axis

• On the x-axis

What is the y-coordinate of any point on the line x = 3?

• It is always 0

• It is always -3

• It is always 3

• It can be any value

What type of line is formed when y is equal to a constant?

• Vertical line

• Diagonal line

• Curved line

• Horizontal line

Where would the point (0, -2) be located on the graph of y = -2?

• On the horizontal line at y = -2

• On the x-axis

• On the y-axis

• On the vertical line at x = -2

What type of line is formed by the equation x = -3?

• Curved line

• Horizontal line

• Diagonal line

• Vertical line

What type of line is formed by the equation y = 4?

• Horizontal line

• Diagonal line

• Vertical line

• Curved line

What is the general rule for the direction of lines when x or y is equal to a constant?

• x = constant results in a vertical line, y = constant results in a horizontal line

• x = constant results in a horizontal line, y = constant results in a vertical line

• Both result in curved lines

• Both result in diagonal lines
