Figure 2 shows some of the results from the investigation. Table 2 shows additional results. Complete Figure 2. You should:
• plot the results from Table 2
• draw the line of best fit.

Table 2: Angle of incidence (degrees): 70, 80 Angle of refraction (degrees): 35, 37

Plotting the points requires finding the correct coordinates on the graph. For (70, 35), find 70 on the x-axis and 35 on the y-axis and mark the intersection. Do the same for (80, 37). The line of best fit should be a smooth curve that goes through the origin (since an angle of incidence of 0° would give an angle of refraction of 0°) and follows the trend of the points, with roughly an equal number of points on either side of the line.
