While a sample size of 28 might not be a large enough to make prove/validate my recommendations, I can tell you that, from my experience, the correct answer to these kinds of questions is typically closer to E than to A.fskilnik wrote: P.S.: in this problem we don´t see any justifiable reason to start the choices evaluation from bottom to the top, with all respect to our colleague's different beliefs.
In short: we see no "scientific" (statistical, information available) arguments for the claim ("the correct answer is typically closer to the bottom than to the top").
(We read the link provided above and, with due respect, we believe the "statistical sample" mentioned there is not significant.)

That said, if it were the case that, with this question type, the correct answer is equally likely to be A, B, C, D or E, then it would make no difference whether one checked the answer choices from A to E or from E to A.
However, if it is, indeed, the case that D and E are more likely to be the answer, then it makes sense to try E and D first.

The ordered pair (0,5) means that the y-intercept of line k is 5. Using the slope-intercept form of a line: y = mx + b, where m is the slope and b is the y-intercept, we see that the equation for line k is y = (1/2)x + 5. Let's see which set of points cannot lie on line k.BTGmoderatorDC wrote:In the xy-coordinate system, line k has slope 1/2 and passes through point (0, 5).
