They are the set of abscissae.
domain
ordered pair
It is called the ordinate.
No, the origin is the point where the x-axis and y-axis meet in the coordinate plane. The x value of an ordered pair is called the abscissa (the y value is called the ordinate).
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
It is called the first coordinate
domain
In the ordered pair (a, b), the object a is called the first entry, and the object b the second entry of the pair. Alternatively, the objects are called the first and second coordinates, or the left and right projections of the ordered pair.
the first number in an ordered pair is the x coordinate it is one of the values that the independent variable has taken on
A set ordered pair is...called a set ordered pair
The abscissa
the first number in an ordered pair is the x coordinate it is one of the values that the independent variable has taken on
It is called the abscissa.
Coordinates
Range
This is a statement; it is not a question.
They're called Coordinates
