The y-axis is drawn vertically from bottom to top with the same origin as the x-axis with positive numbers on top and negative numbers at the bottom. The x-axis is a horizontal line with 0 as the origin, positive numbers on the right, and negative numbers on the left. The numbers placed on the y-axis are called y-coordinates. The numbers placed on the x-axis are called x-coordinates. The variables on the y-axis represent the effect of the cause of the data. The variables on the x-axis represent the cause of the data. It is a vertical plane of a graph in a cartesian coordinate system that gives a numerical value at each point. It is a horizontal plane of a graph in a cartesian coordinate system that gives a numerical value at each point. Let us see the differences: x-axis of a graph There are many differences between the x-axis and y-axis even though it shares the same origin point. The x and y graph consists of the x-axis and y-axis that form the coordinate plane of a graph where numbers are represented for comparison or even forming linear equations. Then to represent these points on the x and y chart, using years on the x-axis and the corresponding population on the y-axis as: We can see here that the location of each point on the graph is noted as an ordered pair where the x-axis or x-coordinate leads the y-axis or y-coordinate. To locate any point on the coordinate plane, we use an ordered pair where the ordered pair is written as (x-coordinate,y-coordinate) or (x, y), where x-coordinate represents a point on the x-axis or perpendicular distance from the y-axis and y-coordinate represents a point on the y-axis or perpendicular distance from the x-axis, therefore it is clear from above that x-axis comes first when writing the ordered pair to locate a point. The image below describes the x and y graph with both positive and negative coordinates.įor example: The population of a city from 2015 to 2020 is given in the X and Y graph table as: Years Any point on the coordinate plane is well defined by an ordered pair where the ordered pair is written as (x-coordinate,y-coordinate) or (x,y), where x-coordinate represents a point on the x-axis or perpendicular distance from the y-axis and y-coordinate represents a point on the y-axis or perpendicular distance from the x-axis. The y-axis on the graph is also known as ordinate. The x-axis on the graph is also known as abscissa. The image below represents the coordinate plane with both axes. The point where the x and y-axis intersect is known as the origin and is used as the reference point for the plane. The horizontal axis is represented by the x-axis and the vertical axis is represented by the y-axis. x-axis and the y-axis that form a coordinate plane for a graph. A x and y graph can be defined by the two axes i.e.
