 * Chapter 3 Section 1


 * IN THIS CHAPTER YOU WILL USE MATHEMATICAL SYMBOLS TO REPRESENT QUANTITIVE RELATIONSHIPS AND EQUATIONS.**

Dx+Ey=F EQUATION 2
SOLUTION: a system of linear equations in two variables in an ordered pair (x,y) that satisfies each equation. CONSISTENT: a system that has at least one solution. INCONSISTENT: a system that has no solutions. INDEPENDENT: a system that has exactly one solution. DEPENDENT: a system that has infinitely many solutions. KEY FACTORS: This has helped lot of people so check it out! []
 * EXACTLY ONE SOLUTION; line intersects at one point; consistent and independent.
 * INFIINTE MANY SOLUTIONS: lines coincide; consistent and dependent.
 * NO SOLUTIONS: lines are parrallel; inconsisten.
