The scatterplot above shows the amount of United States exports of trade goods to Australia in selected years from 1985 to 2015. Also shown is a trend line for the data with equation y = 0.65x + 4.6, which is used to predict the amount, y, in billions of dollars, of United States exports of trade goods to Australia x years after 1985. Based on the equation of the trend line, what is the predicted amount of United States exports to Australia, in billions of dollars, in the year 2030?

This value is derived from an incorrect calculation of the trend line equation, likely using a significantly lower year value for x. As such, it does not reflect the exports predicted for 2030 based on the established trend.

Similar to option A, this choice results from a miscalculation of the equation or an incorrect substitution of x. The figure fails to account for the steady increase indicated by the trend line over the years leading up to 2030.

This option may represent an intermediate prediction based on a year closer to 2025 rather than 2030. However, it does not align with the accurate application of the trend line equation for the specified year of 2030.

This prediction suggests a continuation of exports beyond the established trend line, indicating a higher growth rate than what the equation supports. It inaccurately implies an unrealistic surge in exports that is not reflected in the linear trend established by the data.
