Final answer:
Based on the reference materials provided, none of the answer choices a through d is correct for the equation of the line of best fit.
Step-by-step explanation:
The equation of the line of best fit in slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept. Assuming that you provided the correct graphical plot and calculated the slope and y-intercept from it, here you're comparing the provided options with the general format of the equation. None of the answer choices exactly match the solution given in the reference materials, which is y = −3204 + 1.662x. Therefore, based on the reference materials none of the options a through d is correct.
