| Term | Definition |
|---|---|
| Coordinate plane (coordinate grid) | a two-dimensional plane on which to plot points, lines, and curves |
| x-axis | the horizontal line on a coordinate plane/grid |
| y-axis | the vertical line on a coordinate plane/grid |
| ordered pair | the points to be graphed on the x-axis and y-axis |
| Input-output table | a table which represents how the application of a rule on a value, input(x), results in a different value, output(y) |
| Axes | the vertical and horizontal lines that act as a reference when plotting points on a coordinate plane |
| Origin | the starting point in locating points on a coordinate plane |
| Quadrants | any of the four areas created by dividing a plane with an x-axis and y-axis |
| numerical pattern | a sequence of numbers that has been created based on a rule called a pattern rule (=+ - x /) |
| Additive numerical pattern | a pattern that occurs when a constant non-zero value is added to an input value to determine the output value (y = x + a) |
| Multiplicative numerical pattern | a pattern that occurs when a constant non-zero value is multiplied by an input value to determine the output value (y = ax) |
