I have a physics homework and I was asked to transform $v=v_w+(v_0-v_w)e^{-kt}$ into a linear equation to be graphed. ($v_w$ is one variable that is constant and $k$ is constant.) $v$ is velocity and $t$ is time. Usually $v_0$ is the initial velocity so it's also constant I'm guessing. There is no indication as to what we need to graph on the ordinate or abscissa.
We need to transform the equation as well as say what their $m$ value and $b$ value would be. Help! I've tried playing with natural $\log$ but couldn't get anything that was linear.
