What is the purpose of X and Y?
In mathematics, a function from a set X to a set Y is an assignment of an element of Y to each element of X. The set X is called the domain of the function and the set Y is called the codomain of the function….Tables.

What is the purpose of the x-axis?
The x-axis is the horizontal axis on a Cartesian plane. It is like a number line that tells you the x coordinate for a given point. It allows you to see where a point is on the x-axis by determining how far that point is to the right or the left of the origin.
What is the purpose of the y-axis?
The y-axis is like a vertical ruler. It shows you where an object on a Cartesian plane, a two-dimensional mathematical graph, is in the y (vertical) direction. It is also the starting, or zero, point for measuring how far a point is to the right or left (horizontally) on a graph.
Why is it important to label the X and y-axis on the graph?
Graphs are an excellent way to make a visual representation of data that have been collected. However, without proper labeling, the graph won’t make sense. Therefore, make sure you label the x-axis and y-axis and title your graph so it can be understood by people without having to ask what it represents.
Why is the x-axis horizontal?
On a graph, the range of the independent variable is measured along the horizontal axis and for each value, the resulting value of the function is plotted vertically above the horizontal measurement. Hence the horizontal axis is named the x axis and the vertical axis is the y axis.
Why is title important in graphs?
–A title should be placed at the top of the graph if the graph is to be placed in the laboratory notebook. This helps the reader immediately know what the graph is. The title should be a concise description of what is being graphed (e. g., “Pressure as a Function of Temperature for Nitrogen”).
What needs to be included in the label for each axis of a graph?
Each axis has a label. The axis label shows the name of the variable and its unit. The data points are the values plotted on the graph. Each point is plotted using a pair of values for the variables (the x-coordinate and the y-coordinate).
What is the point of intersection of x-axis and y-axis called?
Thus, the point of intersection of X and Y axes is called origin.
Which axis is also known as category axis?
The horizontal (category) axis, also known as the x axis, of a chart displays text labels instead of numeric intervals and provides fewer scaling options than are available for a vertical (value) axis, also known as the y axis, of the chart.
What is the point of intersection of the x-axis and the y-axis called Brainly?
The center of the coordinate system (where the lines intersect) is called the origin. The axes intersect when both x and y are zero. The coordinates of the origin are (0, 0). An ordered pair contains the coordinates of one point in the coordinate system.
What is the point that represent the x-axis called?
the origin
The point where the X and Y-axis intersect is known as the origin and is used as the reference point for the plane….X and Y-Axis Definition and Difference.

What does the Y axis represent?
The Y axis represents the number of pixels of a particular intensity (the intensities are on the X axis). So a flat histogram simply means that your image has a very equal distribution of grey values (or intensities, let’s forget color for the moment).
Which way is the Y axis and which way is the X?
The x-axis and y-axis are two lines that create the coordinate plane. The x-axis is a horizontal line and the y-axis is a vertical line.
What is the y coordinate for any point on the x axis?
A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin.
What is measured on the Y axis?
The y-coordinate tells you how far up (or down) the vertical y-axis a point is on a graph (measured from the origin). If a point has Cartesian coordinates (2, 4), the point would be 4 units up the y-axis. The image below shows what we mean by a point being 4 units along the x-axis (measured from the origin):
