Systems: Graphing Method page 9.1 - 11 Section 9.1 Focus Exercises Graph each system in the x-y plane provided. Determine 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 . (Be sure to count the grid lines carefully.) Also , verify your answers 1. y = x + 3 y = 3x – 1 2. y = 4 3 x – 2 y = 1 2 x + 3 x + y y + x x + y y + x Solution: ( , ) Solution: ( , ) 3. y = 2 3 x + 2 2x + 3y = - 6 4.
