If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect. Their intersection forms a right, or 90-degree, angle. The two lines in Figure 20 are perpendicular.

Using the slope-intercept form, the slope is −57 .

Using the slope-intercept form, the slope is −5 .

Horizontal lines go left and right and are in the form of y = b, where b represents the y-intercept, while vertical lines go up and down and are in the form of x = a where a represents the shared x-coordinate of all points. All you need to do is remember these.

It is usually easier to remember the horizon is horizontal. When faced with the word vertical, recall that it is not horizontal, and you’ll remember that it is the one that stands up. Vertical stands up straight, horizontal lies down flat.

: a line perpendicular to a surface or to another line considered as a base: such as. a : a line perpendicular to the horizon. b : a line parallel to the sides of a page or sheet as distinguished from a horizontal line.

adjective. at right angles to the vertical; parallel to level ground. flat or level: a horizontal position. near, on, or parallel to the horizon. of or relating to the horizon.

Horizontal line (Coordinate Geometry) Definition: A straight line on the coordinate plane where all points on the line have the same y-coordinate. A horizontal line is one the goes left-to-right, parallel to the x-axis of the coordinate plane. All points on the line will have the same y-coordinate.
