What is the first coordinate set?
A relation is a set of ordered pairs. The first coordinate (usually the x-coordinate) is called the domain and the second (usually the y-coordinate) is called the range.
What is listed first in an ordered pair?
In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate. Note that the x-coordinate is listed before the y-coordinate. Since the origin has an x-coordinate of 0 and a y-coordinate of 0 , its ordered pair is written (0,0 ).
Which of the following refers to the set of all first coordinate?
The domain of the relation is the set of all possible first coordinates.
Are all numbers real?
Real numbers are, in fact, pretty much any number that you can think of. This can include whole numbers or integers, fractions, rational numbers and irrational numbers. Real numbers can be positive or negative, and include the number zero. You cannot add or subject imaginary numbers.
Is the set of first coordinates?
The domain of the relation is the set of all possible first coordinates. When we graph, we think of the first coordinate in terms of x . The range of the relation is the set of all possible second coordinates.
Which of the following referred to the first element in an ordered pair?
The first element of an ordered pair is called its abscissa. The second element of an ordered pair is called its ordinate.
Which coordinate goes first?
The first coordinate (usually the x-coordinate) is called the domain and the second (usually the y-coordinate) is called the range. If you remember from earlier chapters the domain contains values that correspond to the independent variable whereas the range contains values corresponding to the dependent variable.
Which comes first x axis or the Y axis?
To plot a single point on the axis, we start with a coordinate, which is a pair of points each representing a distance travelled on an axis. The x-axis comes first, and then the y-axis. For the point (1,2), the x- coordinate is 1 and the y- coordinate is 2. Here’s how we’d plot that on a graph:
Which is first X or Y?
The x-axis is the horizontal axis and the y-axis is the vertical (straight up and down) axis. When denoting a point in the x-y plane, you always denote the x-value first and the y-value second. That is any arbitrary x-value and y-value are denoted as (x,y).
