HELP MEE PEOPLE. 4.) Graph the two equations to solve the system. What is the solution? x + y = -8 and x - y = 8 (0, -8) (-12, 4) (-4, -4) no solution 5.)Graph the two equations to solve the system. What is the solution? 3x - 2y = 6 and 5x + 3y = -9 (4, 3) (5, 4.5) (0, -3) infinitely many solutions 6.) Is the system consistent or inconsistent? 2x + y = 7 and x - 2y = 7 consistent inconsistent 7.) The system, 6x - 4y = 5 and 9x - 6y = 5, is consistent. True False

    For number 4 just sub x and y into the given equations. The one that is true is the solution. Are you not interested in the process at all?

    4. |dw:1327985774223:dw| To graph the others, assuming you're using pen and paper, for each equation, set y=0 to solve for the x-intercept, and x=0 to solve for the y-intercept. Join the two intercepts to graph the first line. Repeat for the second. For example, #4, x + y = -8 Set y=0, so x=-8. Set x=0, so y=-8. Next step is to join together the two points (-8,0) and (0,-8) to get the first line. You can do similarly for the second line as a check.
