Exploring Horizontal and Vertical Lines

The video tutorial explains the characteristics of horizontal and vertical lines, including their equations and slopes. Horizontal lines are flat, touch the y-axis, and have a slope of zero, with equations in the form of y equals a number. Vertical lines go up and down, touch the x-axis, and have an undefined slope, with equations in the form of x equals a number. The tutorial also covers how to determine the equations of these lines using points and discusses the parallel and perpendicular relationships of these lines with the axes.

What is the slope of a horizontal line?

• Undefined

• Zero

• One

• Infinity

Which axis does a horizontal line always touch?

• x-axis

• y-axis

• Both x and y axes

• Neither x nor y axis

What is the general form of the equation for a vertical line?

• x = my + b

• x = some number

• y = mx + b

• y = some number

What is the slope of a vertical line?
