what is most likely the line of best fit for this scatter plot?

graph shows numbers from 0 to 10 at increments of 1 on the x axis and numbers from 0 to 18 at increments of 2. scatter plot shows ordered pairs 1, 2 and 2, 3 and 3, 6 and 4, 7 and 5, 10 and 6, 11 and 7, 13 and 8, 14 and 9, 17 and 10, 18 and 11, 19 and 12, 20. a line labeled a joins ordered pair 0.5, 0 and 7, 22. a line labeled b joins ordered pairs 0, 0 and 14, 22. a line labeled c joins ordered pairs 0, 1 and 14, 15. a line labeled d joins ordered pairs 0, 2 and 14, 5.

Suppose there is a simple index of three stocks, stock abc, stock xyz, and stock qrs. stock abc opens on day 1 with 4000 shares at $3.15 per share. stock xyz opens on day 1 with 5000 shares at $4.30 per share. stock qrs opens on day 1 with 6000 shares at $4.60 per share. the price of stock abc on day 8 begins at $3.50. the price of stock xyz on day 8 begins at $3.90. stock qrs opens on day 8 with a price of $4.50 per share. assume that each stock has the same number of shares that it opened with on day 1. what is the rate of change of this simple index over 1 week?

9/10 divide by -3/15 as a mixed number
