Straight up and down. On a coordinate plane, the equation
of this type of line is x = a,
where a is a constant.
A method for testing whether a given graph is that of a function. If a vertical line can be drawn that intersects the graph at two or more points, then the graph is not a function. If no such line can be drawn, the graph is a function.
A two-column table whose first column contains input values of a function and whose second column contains output values. The values in the first column are elements of the function's domain, and the values in the second column are elements of the function's range.

Answer 1

Here are the matches between the keywords and their definitions:

1. **Vertical**
Definition: Straight up and down. On a coordinate plane, the equation of this type of line is x = a, where a is a constant.

2. **Vertical Line Test**
Definition: A method for testing whether a given graph is that of a function. If a vertical line can be drawn that intersects the graph at two or more points, then the graph is not a function. If no such line can be drawn, the graph is a function.

3. **Input-Output Table**
Definition: A two-column table whose first column contains input values of a function and whose second column contains output values. The values in the first column are elements of the function's domain, and the values in the second column are elements of the function's range.
