I'm having some issues with this chart, the graph and the question asked post lab. would you please help me solve all these? thank you!

For each point, use the temperature in the middle of your melting point range. After plotting all the points, draw two best fit straight lines to connect at the eutectic composition Upload your graph or Excel file here.
