How is an ordered pair represented?
An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.
What does H 3.2 represent?
h(3.2) represents the height that the rock reaches 3.2 seconds after it was propelled by the slingshot.
How do you determine if a set of ordered pairs represents a function?
How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!
What does Y coordinate mean?
Definition of y-coordinate : a coordinate whose value is determined by measuring parallel to a y-axis specifically : ordinate.
Which statement describes the function h/t )= 210 15t?
Which statement best describes the function h(t) = 210 – 15t? h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.
What does F 0 represent?
Answer and Explanation: The expression f(0) represents the y-intercept on the graph of f(x). The y-intercept of a graph is the point where the graph crosses the y-axis.
What does K mean in math?
y = kx. where k is the constant of variation. Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.
What are some real life examples of ordered pairs?
An ordered-pair number is a pair of numbers that go together. The numbers are written within a set of parentheses and separated by a comma. For example, (4, 7) is an ordered-pair number; the order is designated by the first element 4 and the second element 7.
What are the two numbers in an ordered pair?
P = (6,4)
Which value 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.
What is each number in ordered pair called?
Each number in an ordered pair is called a “coordinate”. The first number is called the “x-coordinate” and the second number is called the “y-coordinate”. These two numbers tell you in which part of the coordinate plane your point lies.
