It is because all measurements are taken from that point: it is the fixed point of reference.

Why is it important to start at the origin when you are graphing points?

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.


How important are the reference points in a coordinate system?

If the reference points are not correct, the location of any coordinate will be incorrect.


What is the difference between graphing a line and graphing an inequality?

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.


How is graphing and graphing a line on a line segment on a coordinate plane different?

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.

What can you say about points whose x coordinates is 0?

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?).


How Translating the point of 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.


What is used to locate points in the coordinate plane?

The x and y displacement from the origin along standard orthogonal axes


How does graphing relationships help you determine whether the relationship is proportional or not?

If the points lie on a straight line through the origin, the two variables are in direct proportion.

What is it called when a x-axis is connected to a y-axis?

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.
