The equation of the line of best fit is y = 50x/3
The missing graph is added as an attachment
From the graph, we have the following points
(x, y) = (0,0) and (3,50)
The equation is then calculated as:
y = (y2 - y1)/(x2 - x1) * (x - x1) + y1
This gives
y = (50 -0)/(3- 0) * (x - 0) + 0
Evaluate
y = 50x/3
Hence, the equation of the line of best fit is y = 50x/3
