  1. 3.1 Systems of Equations by Graphing Goal: Solve a system of linear equations by graphing on the coordinate plane and finding the intersection (x,y)

  2. 1.

  3. 2. 4x - 4y= -12

  4. Definitions: Where do the lines intersect… Consistent & Independent: Two lines that intersect at a single point. Consistent & Dependent: Two lines that are graphed one onto the other. (Same Line = Infinitely Many) Inconsistent: Two lines that do not intersect (Parallel = No Solution)
