I need to change y = 1.378x^-.654
and plot it as lny vs lnx
The question says plot the points x=10, 20, 30...100 for the original y=mx+b function. I've done that but I'm not sure how I'd convert it so that it's in the form of lny = lnx + b for the values x=10, 20, 30...100
I’m still having problems with this. I can derive the equation like you have but I’m unsure of how to graph it on excel or something. When I plug in the values of 10,20,30…100 for x, the graph I get is curved. How would I plot it on a log log plot in excel to get a straight line?
Write out an Excel spreadsheet like this:
The top columns are going to be x, y, log(x), and log(y). Put your x, y data down the x, y columns, then calculate the log(x) and log(y) for each data point. Now make a graph with log(x) for the x data and log(y) for the y data.
