The x-coordinate is a fundamental concept in mathematics and is used to represent the horizontal position of a point on a graph or coordinate plane. It is typically denoted by the letter “x”.

In a Cartesian coordinate system, the x-coordinate is measured along the horizontal axis, also known as the x-axis. The x-axis is usually drawn as a straight line that extends infinitely in both directions. The origin, represented by the point (0,0), is located at the intersection of the x-axis and the y-axis.

To determine the x-coordinate of a point, you need to locate the point on the graph or coordinate plane and draw a vertical line from that point to the x-axis. The intersection of the vertical line with the x-axis gives the x-coordinate.

The x-coordinate can be positive, negative, or zero. Positive x-coordinates are located to the right of the origin, while negative x-coordinates are located to the left of the origin. The x-coordinate of the origin is always zero.

For example, consider the point (2,3). To determine the x-coordinate, draw a vertical line from the point to the x-axis. The intersection with the x-axis is the point (2,0). Therefore, the x-coordinate of the point (2,3) is 2.

In algebra, the x-coordinate is often used to represent an unknown variable or a value that can vary. Equations are commonly written in terms of x, and solving for x involves finding the value(s) of x that satisfy the equation.

Overall, understanding the x-coordinate is essential for graphing, analyzing data, and solving equations in mathematics.
