 Graph of an Equation or Inequality The picture obtained by plotting all the points of an equation or inequality. If there is only one variable, the graph is on a number line. If there are two variables, the graph is on the coordinate plane. If there are three variables, the graph is in three-dimensional coordinates. In general, for n variables, the graph is in n dimensions. For example, the graph of the equation y = x + 1 given below is obtained by plotting all the points with a y-coordinate that is 1 larger than the x-coordinate. See also
