Properties of Horizontal Lines. Equation of Horizontal Line always takes the form of y = k where k is the y-intercept of the line.For instance in the graph below, the horizontal line has the equation y = 1 As you can see in the picture below, the line goes perfectly sideways at y =1.

Practice your knowledge of horizontal and vertical lines: their graphical presentation, their slopes, and their equations.

en.wikipedia.org/wiki/Horizontal_and_vertical

Horizontal lines do not cross each other. Vertical lines do not cross each other. Not all of these elementary geometric facts are true in the 3-D context. In three dimensions. In the three-dimensional case, the situation is more complicated as now one has horizontal and vertical planes in addition to horizontal and vertical lines.

What Is the Difference Between Vertical and Horizontal Lines? Horizontal lines are parallel to the horizon or parallel to level ground. They have a slope of zero and are parallel to the x-axis on a graph.

A line parallel to the x-axis is called a horizontal line. The graph of a relation of the form x = 5 is a line parallel to the y-axis because the x value never changes. Note: A line parallel to the y-axis is called a vertical line. Example 8. Plot the graph of each of the following relations: Solution: Key Terms. horizontal line, vertical line

Graphing Horizontal & Vertical Lines Examples. BACK; NEXT ; Example 1. Graph x = -3. Hmm…there's no y variable in sight, so no matter what value we "plug in" for y, the x-value will always be -3. This makes it a vertical line passing through the x-axis at x = -3. Show Next Step. Example 2.

VERTICAL LINES always have the same x value associated with every y coordinate along the y axis. No matter where you move, up or down, the x coordinate stays LOCKED. Thus vertical lines have equations of the form x = some number.. Examples: x = -2 x = 23.4 x = -0.098. The "t charts" for vertical equations look like this:

Vertical lines help determine if a relation is a function in math. The equation of a vertical line always takes the form x = k where k is any number and k is also the x-intercept. For instance in the graph below, the vertical line has the equation x = 2 As you can see in the picture below, the line goes straight up and down at x = 2
