Term | Definition |
Linear Equation in two Variables | Two variables: x and y. A solution of a system of equations is a point that is a solution of each of the equations in the system.. The point x = 3 and y = 2 is a solution of the system of two. linear equations in two variables. |
Standard Form | Standard Form of a Linear Equation. The "Standard Form" for writing down a Linear Equation is. Ax + By = C. A shouldn't be negative, A and B shouldn't both be zero, and A, B and C should be integers. |
X-Axis | the principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates. |
Y-Axis | the secondary or vertical axis of a system of coordinates, points along which have a value of zero for all other coordinates. |
Abscissa | (in a system of coordinates) the x -coordinate, the distance from a point to the vertical or y -axis measured parallel to the horizontal or x -axis. |
Ordinate | (in a system of coordinates) the y -coordinate, representing the distance from a point to the horizontal or x -axis measured parallel to the vertical or y -axis. |
X-Coordinate | The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate. Also called "Abscissa" |
Y-Coordinate | The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value "5" is the Y Coordinate. |
Viewing Window | The viewing window is the part of the coordinate plane that will be visible on your graphing calculator screen. Remember that you are only seeing a "portion" of an entire graph in your viewing window. |
