    *would

    Draw the graph of: y = (1/x-1), Do you re-arrange it first? If so, what would the first step be? Also, the formula when plotting a graph goes something like change in y/change in x, is change in y at the top of the formula like I've stated or is it actually change in x/change in y?

    No rearrangement needed

    I assume that you know what y=1/x looks like
    This is a simple transformation

    Please use brackets.

    We can't tell whether that is y=\frac{1}{x-1} or y=\frac{1}{x}-1

    Better still learn LaTex.

    Sorry it's the first one, the one where the denominator is x-1

    Ok well assuming you know what y=\frac{1}{x} looks like then this is just a translation one unit in the positive x direction.

    Ok so is it just the graph of y =1/x then a translation of 1 to the right?
