The point (-2, 3) lies in which quadrant?

Lets understand the sign convention of quadrants,

First quadrant        X=positive     and    Y=positive

Second quadrant   X=negative   and    Y=positive

Third quadrant       X=negative   and    Y=negative

Fourth quadrant     X=positive     and   Y=negative

(−2,3)  has X=−2, negative  and  Y=3, positive

The point lies in the second quadrant.
