A point $(x, y)$ has $x = - y$ , with $x$ being a non-zero number, and the point lies in Quadrant II.
What must be true about $x$ ?

Class 9Quadrants and SignsCoordinate Geometry

A $x$ is negative
B $x$ is positive
C $x$ is zero
D $x$ can be either sign

Step-by-Step Solution

In Quadrant II,

x

< 0. (Then

y = - x > 0

, consistent with Quadrant II.) So

x

is negative.

Answer: A)

x

is negative
