Chapter 1: Lesson 1.2 Graphs of Equations Example #1 (HW #9) Example #2 (HW #15) Complete the table and graph y = -2x + 5 x -1 1 2 5/2 y (x, y)

Identifying x-intercepts and y-intercepts An x-intercept is the x value where the graph crosses the x-axis or the x value when y = 0. A y-intercept is the y value where the graph crosses the y-axis or the y value when x = 0. Example #3 (HW #21) Types of Symmetry Look at page 15 Example #4 and #5 (HW #33 and #41)
