My code so far:
figure
plot(x, y);
title('Angle');
xlabel('Horizontal Distance');
ylabel('Height');
I have an image but I don't know how to superimpose the image onto the plot.

Call imshow() to display your image first. Then put "hold on" and do your plotting.

And we are intended to guess what size the image is and what part of the image you want the plot drawn over ?

What are the dimensions of the image, and what is the range of x and y values you want to plot over it?
