Three students are working to find the solution set of this system of equations:
y = 2x + 6
2y = 4x – 2
Use the drop-down menus to complete the statements about each of their methods.
Shannon
Shannon correctly graphs the two lines and sees that they ____. This means the system has ____.
David
David correctly sees that y ____ be equal to both 6 more than twice a number and 1 less than twice a number at the same time.
Alex
Alex correctly concludes that because 2x + 6 and 2x – 1 will ____ be equal, the system has ____.
