How do you write ordered pairs from a function table?
The function table will have two columns, one for the x-value and one for the y-value. Form ordered pairs (x,y) by inserting the values from one row of the table.
How do you find the solutions of ordered pairs?
If a line passes though (10, -3) and (2k, k) the slop of this line is 2/3. How do i find the value of k and state the new ordered pair?
If y varies directly as x and y 36 x 9 then what is the value of x when y 12?
If y varies directly as x and y is 36 when x is 9, then y is always four times the value of x. So if y is 12, then x is 3.
How can you tell if somethings a function?
A function is a relation in which every input value has one output value. so when you have a set of ordered pairs, there can only be one x value corresponding to a y value, so when there is a set like this....{(2,3) (2,4)} the x value has two outputs making this not a function.
If y varies directly as x and y is 6 when x is 72 what is the value of y when x is 8?
y is 2/3.
If y varies directly as x what is the value of y in these ordered pair 8 4 and 4 y?
It is 2.
A set of ordered pairs that assign to each x-value exactly one y-value is called a?
A set of ordered pairs that assign to each x-value exactly one y-value is called a function.
Ordered pairs are used to?
Ordered pairs are used for many things. Anytime you graph a point on a cartesian coordinate system, you have an ordered pair. In fact, all of R^2 is made up of ordered pairs. When you put a value in a function and get one out, you have an ordered pair
What equation best describes the table of ordered pairs?
This kind of question usually accompanies a specific table of ordered pairs. The idea is that the ordered pairs take the form of (x, f(x)) where the first number of the ordered pair x, is a value of the variable for some equation. When that value is used in place of the variable in the equation, we can calculate a specific value. That calculated value appears as the second value of the ordered pair and is represented by f(x) above. Typically the equation is relatively simple, such as a linear equation or a quadratic equation. Therefore, in order to determine the equation, we have to know exactly what the ordered pairs are.

How are ordered pairs and ratios similar?
You can write ordered pairs as ratios to determine if two sets of ordered pairs form a linear or non-linear relationship. In a table of x,y values, the ordered pairs are listed as the x value first, then the corresponding y value. Remove from the table and write as a ratio of x over y, (or y over x, if you like). In a linear relationship, all the ratios of x over y, (or y over x) are equivalent.
In a mapping how many ordered pairs are there for every arrow?
1
What ordered pairs satisfy y equals 8x?
Choose any value for x. Calculate 8x to get the corresponding value for y.
What is the ordered pair for the equation y equals 5x-8?
13
How do you find the solutions of ordered pairs?
If a line passes though (10, -3) and (2k, k) the slop of this line is 2/3. How do i find the value of k and state the new ordered pair?
What is the ordered pair rule?
The rule for a set of ordered pairs is the statement that states the relationship of of a certain value to another value.For example:given the set of ordered pair { (1,2) , (3,4) , (5,6) , (7,8) }we notice that the value of y is increased by 1 as the value of x varies.For instance, in the first ordered pair which is (1,2) where 1 is x and 2 is y such that (x,y), 1 increased by 1. In other words, x is increased by 1.So we say that the rule of the ordered pair is:{(x,y) | y = x + 1 }read as "The set of ordered pairs such that y is equal to x plus one"
What is the math term for ordered pairs with exactly one y value for any x value?
I believe it is a function, because a vertical line would only cross it once.
