Algebra I Module 3, Topic C, Lesson 16

Student Outcomes

  • Students discover that the multi-step and exact way of solving |2x - 5| = |3x + 1|  using algebra can sometimes be avoided by recognizing that an equation of the form f(x) = g(x) can be solved visually by looking for the intersection points of the graphs of y = f(x) and y = g(x).
