Understanding Vertical and Horizontal Lines

This video tutorial teaches how to graph vertical and horizontal lines. It explains that vertical lines are represented by equations of the form x = constant, and horizontal lines by y = constant. The tutorial provides examples and exercises to illustrate these concepts, including plotting points on a coordinate plane and connecting them to form lines. It also covers solving equations to graph lines and emphasizes the relationship between the equations and their graphical representations.

What does the equation x = 3 imply about the value of x?

• x can be any value

• x is always 3

• x depends on y

• x is always 0

What happens to the value of x in the equation x = 3 when y changes?

• x changes with y

• x remains constant

• x becomes zero
