1. TAKS Algebra I Review for Benchmark Day 2

2. Graphing & Systems Graphing Linear Inequalities Quadratics Parameter Changes Interpreting Graphs *Use graphing calculator & trace Systems Graphing Method Substitution Method Elimination Method Matrices Method (Algebra II)

3. Linear y = mx + b where m = slope (rise/run) b = y-intercept (0,b) y = # horizontal line x = # vertical line y- y 1 = m (x – x 1 ) where m = slope point (x 1,y 1 )

4. Inequalities:, ≤, ≥ y > mx + b Dividing or Multiplying by a negative Expressing Functions as compound Inequalities

5. Quadratics y = ax² + bx + c Solve for x-intercepts (roots) by Factoring Quadratic Formula – on formula chart Vertex (Line of Symmetry)

6. Parameter Changes Parent Functions Linear Quadratic Absolute Shifts Use graphing calculator Original Graph only Add second graph with change to compare

7. Interpreting Graphs Just like science Look at the title Look at the labels of x & y axis Think as “x” is moving forward/increasing “y” is doing what?

8. Systems Where two or more equations share a common answer(s) (order pair) Graphing y = 2/5x + 3 y = -1/4x + 3 Substitution y = 4x + 1 3x + 2y = 35 Elimination 3x + 2y = 14 -3x + 8y = 26
