Official Solution:


We’ll go for LOGICAL because that is our first choice in Data Sufficiency.

We are asked to find the y-coordinate of a specific point on the line segment.

(1) A line segment’s slope and a point on the line are 2 out of the 3 pieces of information needed to find the line’s equation – but that’s not enough to identify a specific point on the segment! Insufficient. (A) & (D) are eliminated.

(2) The same is true: two points on a line segment are enough to find the segment’s equation, not a specific point on the line. (B) is eliminated.

Combining the statements is of no help, as they both give sufficient information to draw the line, but tell us nothing about the specific point \((p,q)\). (C) is eliminated.


Answer: E

Hi,

using just statement 2:
q-6/1-p=q-2/p-3=6-2/1-3

I get q=6,

So, statement 2 is sufficient. (B)
Please let me know if I am missing something.
