a. Give an example of an inconsistent system of equations consisting of 3 planes that are each parallel to the y-axis, but no pair of planes are parallel to each other. b. Give an example of a consistent system of equations consisting of 3 planes that are each parallel to the y-axis. Solve the system. Show work.

x + 3y  =  12 Y=-1/3X-3 b) Classify the lines formed by the system as parallel, perpendicular, or neither. parallel. perpendicular     neither (c) Is the system of equations independent, inconsistent, or dependent? independent inconsistent     dependent

6.) The graph of the system of equations is shown below. What is the solution to the system of equations? 3 2 6 5 4 3-2-1 1 2 3 4 -2 -3 -5- The solution is (-3, -1) because the solution to the system must represent the x- intercepts to both equations. The solution is (1, -3) because the solution to the system must represent the y- intercepts to both equations. The solution is (-2, -1) because the solution to the system must satisfy both equations simultaneously. The solution is (1, 2) because the solution to the system must satisfy one equation or the other.

3. Solve the system of equations by graphing. (x+Y3D6 X-y D0
