The sterplot has 12 data points. The data points are in a linear pattern trending up from left to right.

Question

Twelve data points are shown in the sterplot. A line of best fit for the data is also shown. At $x equals 1,200$ , which of the following is closest to the y-value predicted by the line of best fit?

Accepted Answer

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 = 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 = 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 = 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 = 600 .
