Sorry about the handwriting! For (a), simplify the more complex version into a more readable form. We find that we have a reciprocal graph. Since the question wants us to solve for m such that the given line intersects the reciprocal graph at more than one point, we need to find equations for the asymptotes of the given reciprocal graph. Our value of m lies between these two asymptote gradients. For (b), start by transforming the given equation into a more readable version. Since k is a constant, we can simplify the equation such that x variables are on one side, and the y variable (6-k) is on the other. Once you’ve solved this, values for k should become apparent.
