What is the set of all first coordinates from each ordered pair?
The domain.
What is the point of origin in an ordered pair?
The origin, in the Cartesian coordinate system, is the point with coordinates (0, 0). So, if you have another ordered pair, the ordered pair doesn't "have an origin"; rather, the origin is another point.
A pair of numbers used to locate a point on a graph?
A pair of numbers that are used to locate a point on a graph is called a ordered pair and is expressed as (x,y) where x is the location horizontally and y is the location vertically. For example the ordered pair (3,5) would be 3 to the right and 5 up away from the origin of the graph (0,0).Is called a ordered pair================ They are called coordinates. They need not be horizontal and vertical distances as suggested by the answer above. They could be polar coordinates which are the angle from the horizontal (anticlockwise), and distance from the origin.
The first number in an ordered pair is the x-value and the second number is the y-value These two numbers are called the of the point?
Cartesian coordinates. Also, the abscissa and the ordinate.
How would you determine the domain and range from a list of ordered pairs?
The domain is the set of the first number of each ordered pair and the range is the set of the second number.
