The Vertical Number Line Of A Coordinate Graph
A vertical line has no slope. Or put another way, for a vertical line. What is a coordinate plane? A coordinate plane is formed when a vertical number line overlaps a horizontal number line, forming a 2 2 dimensional gridded surface. It can also be called a coordinate grid.
The quadrants are labeled \(q1\text{,}\) \(q2\text{,}\) \(q3\text{,}\) and \(q4\) and proceed counterclockwise around the plane as shown in the graph at the left. A vertical line is a straight line that runs from the top to the bottom of a graph or chart. The point at which the lines intersect is called the origin. A jumping frog is starting at the origin. Use the interactive to practice identifying the equations of a given horizontal or vertical line.
