For this activity I will give myself a score of 9. I was able to fit the reconstructed plot to the original image, however, both the x and y axes are off by around 1 - 3 divisions. this happened because the image i scanned is skewed, so the divisions in the image are not equally spaced.

to compute for the conversion formula, i obtained the pixel positions of the x and y axes and looked for an appropriate conversion factor. Afterwards I subtracted the position of the origin. I was able to obtain the following formula;

x axis: (xpixel-65)/43.4375
y-axis: (ypixel-529)/-42.9167
my origin is at (65,529)
