If a set of ordered pairs is not a relation can the set still be a function?
If a set of ordered pairs is not a relation, the set can still be a function.
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 can you determine that a set of ordered pairs are a graph table diagram equation a function or mere relation?
In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
What is the y-intercept of the line y6x-9 in ordered pairs?
15
Are these ordered pairs in direct variation -1 0 3 2 9 6?
No. For direct variation, any order pair with a 0 in it MUST be (0,0).
