    the transformation that gives a straight line graph

    Can you clarify this question for me:

    Consider the relation y=25e^3x ,the transformation that gives a straight line graph is:

    1)lny is plotted against ln(3x)
    2)lny is plotted against lnx
    3)y is plotted against x
    4)y is plotted against lnx
    5)lny is plotted against x

    If y = 25 e^{3x} then \ln y = \ln 25 + \ln e^{3x} = \ln 25 + 3x so here it's  \ln y \; \text{vs}\; x
