Lines and graphs Abscissa: a graph's horizontal line, often known as the x-axis. An arc is a part of a circle's circumference. Axis: One of the lines that makes up a graph. It can be the X or Y axis.

I The x-axis is the horizontal line used to calculate the location of any point in the Cartesian plane. The y-axis is the vertical line used to identify the location of any point in the Cartesian plane. These two axes are called "coordinate axes".

The vertical line in the graph is referred to as the Y-axis. The vertical reference line is known as the Y-axis in the Cartesian coordinate system. It is also called the plumb line or zero level.

In mathematics, the y-axis (or simply axis) is the second dimension of **a coordinate plane**. The y-axis divides the plane into **two regions**, above and below it. Points below the axis are called negative numbers while those above it are positive numbers. The y-axis passes through the origin, which is the only point at which all three axes meet.

The word "y" here does not stand for anything special. It's just another letter like "x". This axis has nothing to do with the y-coordinate of **any object**. It's just another way to divide up the plane into **two parts**.

As you can see from the image, there are several other ways that the plane can be divided up into two parts. The x-axis goes across the page, dividing the plane into four quadrants. From left to right, these go from negative numbers to positive numbers, passing through zero. The y-axis goes down the page, dividing the plane into three sections. From top to bottom, these go from negative numbers to positive numbers, again passing through zero.

A bar graph **A bar chart** is a graph that has **rectangular bars** with lengths that are proportionate to the values they represent. The chart's one axis reflects the precise categories being compared, while the other axis displays **a discrete value**. Bar graphs are used when the data can be visualized in terms of differences among items within a group.

Bar charts are one of the most common types of charts used in statistical graphics. They are particularly useful for comparing several groups or levels of an independent variable, because the distribution of variables such as income, age, and gender can be shown on the same scale as the categories of a categorical variable like country. Also, they are easy to read due to the fact that all information necessary for interpreting the graph is included on the plot itself.

The term "bar chart" comes from the use of bars to show individual score marks or categories. Before bar charts, column diagrams were commonly used for showing data in this way. However, column diagrams are difficult to interpret because it is not clear how much each category contributes to **the total score**. Therefore, many statistics textbooks recommend using bars instead.

In addition to showing differences between groups, bar charts are also useful for showing changes over time within groups. For example, antibiotics resistance rates among different bacteria can be plotted against the years since the beginning of antibiotic usage to show how resistance has increased over time for each species.

A horizontal line is a line that runs parallel to the x-axis. Because the x value never changes, the graph of a relation of the type x = 5 is a line parallel to the y-axis. Relationships between variables can be represented by lines on a coordinate plane. Such lines are known as linear relationships because they represent a ratio or proportion between the two quantities being compared.

A Vertical Line Graphing Example This is exactly how the equation x = 3 x = 3 x = 3 x = 3 x = 3 x = 3 x = 3 x = 3 x = 3 x = 3 So we can plot the points on the x, y, and xy axes to see how it appears. It is, as you can see, a vertical line parallel to the y-axis and going through the point (3,0).

Line Forms For example, line (20,100,200,100) generates a horizontal line on the graphics screen from position (20,100) to position (200,100). Vertical axis: In this case, the x-axis values remain constant while the y-axis values vary. For instance, line (50,40,50,200); draws **a vertical line** from position (50,40) to position (50,200).
