Here are the essential concepts you must grasp in order to answer the question correctly.
Constant Functions
A constant function is a type of function where the output value remains the same regardless of the input value. In the case of the equation y = 5, the function outputs the value 5 for every x-value. This results in a horizontal line on the graph, indicating that no matter how far you move along the x-axis, the y-value will always be 5.

Graphing Linear Equations
Graphing linear equations involves plotting points that satisfy the equation and connecting them to form a straight line. For the equation y = 5, the line is horizontal, which means it runs parallel to the x-axis. Understanding how to graph linear equations helps in visualizing the relationship between variables and interpreting their behavior.

Coordinate Plane
The coordinate plane is a two-dimensional surface defined by a horizontal axis (x-axis) and a vertical axis (y-axis). Each point on the plane is represented by an ordered pair (x, y). In the context of the equation y = 5, all points on the line will have a y-coordinate of 5, while the x-coordinate can take any real number value, illustrating the concept of a horizontal line in the coordinate system.
