Please help with above problem.
Hi Anaira,
Given that PQ is parallel to Y-axis, and PR is parallel to X-axis, we can deduce that the x-coordinate of P and Q are the same, and the y-coordinate of P and R are the same.
S1: The x-coordinate of point Q is -1 means that the x-coordinate of point P is -1.
However, we do not have P's y-coordinate. Insufficient.
S2: The y-coordinate of point R is 1 means that the y-coordinate of point P is 1.
However, we do not have P's x-coordinate. Insufficient.
S1 & S2:
The coordinates of P are; (-1, 1), thus the sum =
0.
