Is (8, -1) a solution of the system, 2x + 3y = 13 and x - y = 9? (Points : 1) yes no 2. Is (-2, -5) a solution of the system, 3x + 2y = 4 and 2x - 5y = -29? (Points : 1) yes no 3. Graph the two equations to solve the system. What is the ordered pair solution? x + y = 6 and x - y = 4 (Points : 1) (4, 2) (6, 2) (5, 1) no solution 4. Graph the two equations to solve the system. What is the solution? 1/2 x - 2y = 4 and 4y - x = -8 (Points : 1) (-2, 0) no solution (3, 4) infinitely many solutio

    1) yes 2) no -- it is (-2, 5) 3. (5,1) Graph at link: http://www.wolframalpha.com/input/?i=%28x+%2B+y+%3D+6%29+and+%28x+-+y+%3D+4%29 4. infinitely many solutions - graphs coincide. See graphs at link: http://www.wolframalpha.com/input/?i=%28%281%2F2%29+x+-+2y+%3D+4%29+and+%284y+-+x+%3D+-8%29
