Best ResponseYou've already chosen the best response.0For 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?

Best ResponseYou've already chosen the best response.24. dw:1327985774223:dw To graph the others, assuming you're using pen and paper, for each equation, set y=0 to solve for the xintercept, and x=0 to solve for the yintercept. 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.
