Download the data file Class10Data1.mat from eCampus. Write a function in which you: a) plot the data using a scatter plot of y vs. x to check that a linear model makes sense, b) use polyfit to fit a linear model to the data and output the slope and intercept, and c) plot the best-fit line on the same graph as the scatter plot. I'm having trouble with making the function file and loading that .mat file into matlab and using the data from the mat file to make the scatter plot. This is what I have

Your output should look like this :
