  2. Solve the system using the substitution method. 1. 2x – y = -1 -3x + 4y = -6

  3. Solve the system using the elimination method. 2. 2x – 5y = -8 -3x + 4y = 5

  4. Solve the system using Cramer’s Rule. 3. 7x – 5y = -58 -3x - 4y = -12

  5. Solve the system using any algebraic method. 4. 7x – 3y + 5z = 15 -3x + 2y + 4z = 3 4x – 9y – 3z = 26 1 2 3 4 5

  6. Evaluate the determinant of the matrix.

  7. Evaluate the determinant of the matrix.

  8. Tell whether the given ordered triple is a solution of the system. Make sure to show work.

  9. Graph the system of inequalities. Right 2 Up 1 Down 2 Right 3 Shade Left Shade Down Up 1 Shade Up Right 2 Down 2 Right 3
