When solving a system of linear equations with two unknowns, which of the following statements is/are true? I. If the system has no solution, the equations represent the same line. II. If the system has infinitely many solutions, at least one variable in the general solution will be arbitrary. III. The solution to the system of equations must satisfy only one of the equations in the system.      A.  Only II and III are true.  B.  Only I is true.  C.  Only II is true.  D.  Only I and II are true.  E.  Only III is true.

1. What is the solution to the system of linear equations shown in the graph below? -4 -3 -2 -2 구

Solve the following system of linear equations: x-y = 4 -4x+4y= -16 Which one of the following statements best describes your solution:A. There is no solution.B. There is a unique solution.C. There are 2 solutions.D. There are infinitely many solutions. Statement: D- There are infinitly many solutions  Solve for y in terms of x

3. Solve each system of equations using the algebraic method of your choice. (Do not solve by graphing!) Show all of your work completely. State the solution set clearly. Write NO SOLUTION (0) or INFINITELY MANY SOLUTIONS if appropriate. If there are infinitely many solutions, use set builder notation to define the ordered pairs in the solution set. a. b. C. -X- 1 3 x- J5x- 1 y = 2 x + 3 4 1 2 y = Y 6 1 vit 5x-6y=-4 -4x+5y=3 2 13 6 = = 4 x y-5 1 + 12 15 60
