A student is assessing the correlation between the number of workers in a factory and the number of units produced daily. The table below shows the data:

Number of workers (x) 0 10 20 30 40 50 60 70 80 90 Number of units (y) 2 52 102 152 202 252 302 352 402 452

Part B: Write a function which best fits the data. (3 points)

Part C: What does the slope and y-intercept of the plot indicate? (3 points)
