    Use the short formula.. y - y1 = m(x-x1) y - (-5) = -2/3 (x - 2)

    Lets start this over. Basically you have got your slope and your b, so you are pretty much set up.

    he said y = 2x/3 - 19/3 you cant substract that correct

    so it would be 2x/3 - y = -19/3

    y - y1 = m(x-x1) y - (-5) = -2/3 (x - 2) y+5=-2/3x + 4/3

    then i understand the 2/3x - y = 4/3 - 5 after this is where i get confused

    From there, you must but it into standard form, having all the x's and y's on one side. Subtract y, and then subtract 4/3. Giving you 11/3=-2/3x-y

    Okay, then you can get rid of the fractions by multiply each side by 3.
