Solve the system by graphing.
3x+y=6
3x-y=0

This is how far I got:
(First line): y=-3x+6
(Second line): y=3x

I'm not sure how to graph the second line. Is the y-intercept (0,0) and the two lines meet at (1,3)?

  • Algebra -

    first of all do you have a graphing calculator?

    Well using my TI-83

    and keying in the equations I got

    (1,3) at the intersection of the 2 lines

    but for the y intercept it was aproximately

    (0,6)

    No, I don't have a graphing calculator. Thanks for your help.
