Plz help! I'm on the quiz right now. A scatter plot is shown below:

Graph shows numbers from 0 to 10 at increments of 1 on the x axis and number s from 0 to 10 at increments of 1 on the y axis. Scatter plot shows ordered pairs 1, 1.5 and 2, 2 and 3, 3 and 4, 4 and 5, 6 and 6, 6.6 and 7, 7 and 8, 8 and 9, 8.9 and 10, 10.

Which two ordered pairs can be joined to draw most accurately the line of best fit on this scatter plot?

(0, 0.5) and (10, 10)
(0, 4.5) and (7, 10)
(5, 0) and (10, 5)
(5, 0) and (9, 4)
