You don't have to show outputs as you don't have the data files obviously so please just the code that'll be able to give the correct outputs.

1. (15 pts.) Download the data file Class10Data1.mat from eCampus. Write a script 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. Your output should look like this: Figure 2 File Edit View Insert Tools Desktop Window Help 80 70 60 40 30 20 2 10 12 4 16 18 20 slope is 4.269476, and intercept is 1.921243 1. (15 pts.)
