Match the vocabulary words with the correct definitions. 1. relation
a test used to determine if a graph is a function; states that a vertical line can only go through one point on the graph to be a function
2. vertical line test
a set of ordered pairs
3. function
a value generated by a function when an input value is substituted into the function and evaluated
4. output
a group of two numbers written in the form (x, y) where the x value represents a horizontal position and the y value represents a vertical position
5. ordered pair
a relation in which for any given input value, there is only one output value
6. mapping diagram
a value that is substituted in for the variable in a function in order to generate an output value
7. input
a table or diagram that represents a mathematical relation

Here are the vocab:

Step-by-step explanation:

1. Relation - a set of ordered pairs

2. Vertical line test - a test used to determine if a graph is a function; states that a vertical line can only go through one point on the graph to be a function

3. Function - a relation in which for any given input value, there is only one output value

4. Output -  value generated by a function when an input value is substituted into the function and evaluated

5. Ordered pair - a group of two numbers written in the form (x, y) where the x value represents a horizontal position and the y value represents a vertical position

6. Mapping Diagram - a table or diagram that represents a mathematical relation

7. Input - a value that is substituted in for the variable in a function in order to generate an output value

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
