Questions and Answers
  • 1. 

    Graph this system and solve.

  • 2. 

    Graph this system and solve.6x - 3y = -152x + y = -3

    Explanation
    The given system of equations can be represented by two lines on a graph. The first equation, 6x - 3y = -15, can be rewritten as y = 2x + 5. The second equation, 2x + y = -3, can be rewritten as y = -2x - 3. By plotting these lines on a graph, we can find the point of intersection, which is the solution to the system. In this case, the lines intersect at the point (-2, 1), which is the correct answer.

  • 3. 

    Graph this system and solve.-2x + y = -11-x - 9y = -15

    Explanation
    The given system of equations is graphed and solved to find the point of intersection. The first equation is -2x + y = -11 and the second equation is -x - 9y = -15. By substituting x = 6 and y = 1 into both equations, it is found that both equations are satisfied. Therefore, the point (6, 1) is the solution to the system of equations.

    Solve with elimination.

  • 8. 

    Solve with elimination.

  • 9. 

    Solve with elimination.

  • 10. 

    Solve using graphing, substitution, or elimination.

  • 11. 

    Solve using graphing, substitution, or elimination. 

  • 12. 

    Solve using graphing, substitution, or elimination.

    Explanation
    The given answer (2, 0) is already in the correct format of an ordered pair. It represents the x-coordinate as 2 and the y-coordinate as 0. This means that when graphed on a coordinate plane, the point will be located at the intersection of the x-axis and the line passing through the point (2, 0). The question asks to solve using graphing, substitution, or elimination, but since no equation or problem is provided, it is not possible to determine which method was used to arrive at the answer.
