Section 4-5 Graphing linear Equations Using a Table of Values  Rules and Purpose of Columns  First Column the first column is used for the x-coordinate, any number can be used for the X-coordinate but it would be simpler to use a smaller number, such as a 1, 0, and -1.

Second Column the second column is used for substitution. You substitute the x-coordinate into the equation to solve for the y-coordinate. (y =mx+b)

Third Column The third column is used for the y coordinate, which is found when the x coordinate is substituted into the equation.

Fourth column the last column is used for the ordered pair. The ordered pair is found once the x and y coordinate are found you insert them into the fourth column.

 Examples(easiest to hardest)

A linear equation is the equation of a line. Linear equations can often be written in the form Ax+By=C GRAPH LINEAR EQUATIONS: The graph of a linear equation is a continuous line. It extends beyond the endpoints in each direction and represents all the solutions of the linear equation. Also every ordered pair on this line satisfies the equation
