Review: Distances in the Coordinate Plane
Explanation
In this question, point P resides at the coordinates (4,
2). The not-shown point Q is "the same distance from the y axis as point P is from the x
axis." That little phrase means that since point P has a y coordinate of 2, point Q will have an x coordinate of 2, and will thus be (2,
?). It will therefore have coordinates (2, 4), since it is equidistant from y = x.
Finally, since point R is the same distance from each axis as point Q, it must
have an x coordinate of 
and a y coordinate
of 
.
The correct answer is (C).
