What's on the worksheet

  1. Solve each system by graphing, then check by substitution:
    y = x + 3 and y = -2x + 6y = -\dfrac{1}{3}x + 2 and y = x - 2x + 2y = 6 and x - y = 3y = -4 and 3x - 2y = 2
  2. Find two pairs that solve one equation but not the system, and the real solution.
  3. Write a second equation so the system has no solution or infinitely many.
  4. Graph three lines on one grid and find where they cross.
  5. Decide how many solutions a system with two known solutions has.
  6. Word problem: Mia and Owen gathering petition signatures.
