The x-axis represents distance from the Sun (AU), and the y-axis represents density (g/cm³).

The scatterplot above shows the densities of seven planetoids, in grams per cubic centimeter, with respect to their average distances from the Sun in astronomical units (AU). A line of best fit is also shown. According to the line of best fit, which of the following best approximates the density of a planetoid that is 0.4 AU from the Sun?
