It is because all measurements are taken from that point: it is the fixed point of reference.
when graphing a line you simply plot the points based on the ordered pairs and connect the dots; there you have a line. An inequality graph refers to the shaded region of the coordinate plane that does not coincide with the line, hence the term, inequality.
If there is no 'Y' coordinate then it is considered the 'origin'.
Origin is at points (0, 0) in coordinate geometry. If you are shifting/translating the origin, you have to add the respective x and y coordinates of the new origin with respect to the old origin to get the coordinates of the new origin.
If the points lie on a straight line through the origin, the two variables are in direct proportion.

It is important for beginners because the coordinates of the graphing points are measured from the origin. More expert users don't need to do so.
If the reference points are not correct, the location of any coordinate will be incorrect.

Graphing involves plotting points or shapes on a coordinate plane, representing various mathematical relationships. Graphing a line means drawing an infinite straight path extending in both directions, defined by a linear equation. In contrast, graphing a line segment involves drawing a finite portion of a line, characterized by two endpoints, and represents only the points between those endpoints. Thus, while both involve linear relationships, the scope and representation differ significantly.
X-Y Coordinates Origin Quadrants Points
If there is no 'Y' coordinate then it is considered the 'origin'.
X-Y Coordinates Origin Quadrants Points The proper answer is a QUADRANT. The others are objects that may be found on a coordinate plane. Points are listed but not lines (why not?).
Origin is at points (0, 0) in coordinate geometry. If you are shifting/translating the origin, you have to add the respective x and y coordinates of the new origin with respect to the old origin to get the coordinates of the new origin.
The x and y displacement from the origin along standard orthogonal axes
If the points lie on a straight line through the origin, the two variables are in direct proportion.

When the x-axis is connected to the y-axis, it typically refers to the Cartesian coordinate system, where the two axes intersect at a point called the origin. This system allows for the representation of points in a two-dimensional space using ordered pairs (x, y). The connection at the origin is fundamental for graphing functions and analyzing relationships between variables.
