What is a coordinate ray?
Click to flip
A coordinate ray is a part of a line that starts at a point (usually the origin) and extends infinitely in one direction along the coordinate axis.
Click to flip
Where does a coordinate ray usually start?
Click to flip
It usually starts at the origin of a coordinate system.
Click to flip
Which direction does a coordinate ray extend?
Click to flip
It extends infinitely in one direction from its starting point.
Click to flip
How is a coordinate ray represented in a coordinate plane?
Click to flip
It is represented by a straight line starting at a point on one of the axes and extending outwards.
Click to flip
What is the difference between a line and a ray in geometry?
Click to flip
A line extends infinitely in both directions, while a ray starts at a point and extends infinitely in one direction.
Click to flip
What is the significance of the origin in a coordinate system?
Click to flip
The origin is the point (0,0) in a coordinate plane where the x-axis and y-axis intersect, often serving as the starting point for rays.
Click to flip
What is another term often used to describe a coordinate ray?
Click to flip
It is sometimes referred to as a half-line.
Click to flip
In which mathematical concepts is understanding a coordinate ray important?
Click to flip
It is important in learning about vectors, plotting graphs, and solving linear equations.
Click to flip
Can a coordinate ray exist in 3-dimensional space?
Click to flip
Yes, a coordinate ray can be extended in 3D space, starting from the origin and extending along one of the axes.
Click to flip
What is an example of a real-world application of a coordinate ray?
Click to flip
Navigational systems use the concept of a coordinate ray to plot courses from a fixed point in one direction.
Click to flip
How does a coordinate ray differ from a segment?
Click to flip
A segment is a part of a line bounded by two distinct endpoints, while a ray starts from one point and extends infinitely in one direction.
Click to flip
What do you call the point where a coordinate ray begins?
Click to flip
This point is called the endpoint.
Click to flip
Can a coordinate ray be used to represent numbers on the number line?
Click to flip
Yes, the ray on a number line can represent values extending from an endpoint, such as whole numbers extending infinitely.
Click to flip
Is it possible for two coordinate rays to form an angle?
Click to flip
Yes, two coordinate rays with a common endpoint can form an angle.
Click to flip
What role does a coordinate ray play in graphing inequalities?
Click to flip
A coordinate ray can be used to represent solutions to inequalities on a number line, showing all numbers greater or less than a given value.
