    An infinite number of points lie on a line

    If you want any point, you can let x=0 to get 6y=2 y=1/3 you would have the point (1, 1/3) on the line

    err that was a mistake, the point i got was (0, 1/3) but (1, -1/3) might be a point... let's see :)

    if x=1, then 3+6y=2 6y= -1 y= -1/6 So (1, -1/3) would not lie on th eline

    well we have the answer then. We just solved for the point on the line when x=1 and got (1, -1/6) :) Do you understand the process though of how we got the answer?

    I do...I just plugged in all the answers to the first equation (3x+6y=2) and (1,-1/6) was the only answer that worked...thats another way to solve it right?
