These are the same explanations that are featured in my "Guides to the Official Guide" PDF booklets. However, because of the limitations of HTML and cross-browser compatibility, some mathematical concepts, such as fractions and roots, do not display as clearly online.

Solution and Metadata

Question: 25
Page: 155
Difficulty: 3 (Very Easy)
Category 1: Geometry > Coordinate Geometry > Other

Explanation: To find the x - coordinate, count the number of units on the x - axis (the horizontal one) from the intersection of the axis. Do the same vertically for the y - coordinate. Since the x - coordinate is to the right of the origin, it is positive; since the y - coordinate is below the origin, it is negative. Thus, since the x - coordinate is 7 units from the origin and the y - coordinate is 5 units from the origin, point V is (7, - 5), choice (E).
