Explanation

Choice C is correct. On the line of best fit, an x-value of $1,200$ corresponds to a y-value between $10$ and $12$ . Therefore, of the given choices, $11$ is closest to the y-value predicted by the line of best fit at $x equals 1,200$ .

Choice A is incorrect. This is the integer value closest to the y-value predicted by the line of best fit at $x equals 1,800$ .

Choice B is incorrect. This is the integer value closest to the y-value predicted by the line of best fit at $x equals 1,500$ .

Choice D is incorrect. This is the integer value closest to the y-value predicted by the line of best fit at $x equals 600$ .
