A scatterplot displays the relationship between two variables, x and y. The data points generally follow a positive linear pattern, but are somewhat spread out. The line of best fit appears to pass through approximately (0, 4) and (6, 13).
Which of the following equations best models the line of best fit for this data?
y = 1.5x + 4
y = 2x + 3
y = 1.2x + 5
y = x + 4.5
