Systems: Substitution Method page 9.2 - 11 Section 9.2 Focus Exercises Use the substitution method to find the solution, if possible. If the lines are parallel, indicate that by writing inconsistent ; if the lines are the same line, indicate that by writing dependent . Also, verify your answers. 1. y = 3x + 9 y = - 2x 1 2. y = x + 3 y = 3x 1 3. x + y = 2 y = 1 2 x 4 4. y = 2 3 x + 2 2x + 3y = - 6 5. y = 2x
