e.g. y = -2x is a rule. if we wish to graph this we get ourselves some coordinates by creating a table.** ^ traditionally X and Y but can be other letters. (: - choose some appropriate consecutive numbers. - use rule to find rule. - draw a graph using the coordinates.
 * Finding The Rule. =)
 * X || -2 || -1 || 0 || 1 || 2 || 3 || 4 ||
 * Y || 4 || 2 || 0 || -2 || -4 || -6 || -8 ||
