Three students are working to find the solution set of this system of equations: y = 3x + 10 2y = 6x – 4 Use the drop-down menus to complete the statements about each of their methods
Mia:
Mia correctly graphs the two lines and sees that they ( Intersect, do not intersect, are on the same line) This means the system has (one, zero, Infinitely many) solution(s)
Roberto:
Roberto correctly sees that the y ( can, cannot) be equal to both 10 more than three times a number and 2 less than three times a number at the same time.
Delmar:
Delmar correctly concludes that because 3x + 10 and 3x - 2 will ( Sometimes, never, always) be equal, the system has (one, zero, Infinitly many) solution(s)
