Modded SAT Question Bank by Abdullah Mallik

The scatterplot shows the relationship between two variables, x and y. A line of best fit for the data is also shown.

  • The scatterplot has 11 data points.
  • The data points are in a linear pattern trending down from left to right.
  • A line of best fit is shown:
    • The line of best fit slants down from left to right.
    • 6 points are above the line of best fit.
    • 5 points are below the line of best fit.
    • The line of best fit goes through the following approximate coordinates:
      • (28 comma 6)
      • (33 comma 1.5)

At x=32, which of the following is closest to the y-value predicted by the line of best fit?

  1. 0.4

  2. 1.5

  3. 2.4

  4. 3.3

Correct Answer: C
Rationale

Choice C is correct. At x=32, the line of best fit has a y-value between 2 and 3. The only choice with a value between 2 and 3 is choice C.

Choice A is incorrect. This is the difference between the y-value predicted by the line of best fit and the actual y-value at x=32 rather than the y-value predicted by the line of best fit at x=32.

Choice B is incorrect. This is the y-value predicted by the line of best fit at x=31 rather than at x=32.

Choice D is incorrect. This is the y-value predicted by the line of best fit at x=33 rather than at x=32.
