If the points have both positive y-values and x-values it is quadrant 1
If the points have a negative x-value and a positive y-value it is quadrant 2
If the points have both negative y-values and x-values it is quadrant 3
If the points have a positive x-values and a negative y-value it is quadrant 4
Quadrant I
The point of origin is not in any quadrant. In fact, any point on the X or Y axis is not in a quadrant. In order for a point to be in Q1, Q2, Q3 or Q4, it must not be on an axis.
In the 1st quadrant
The point (2, 3) is located in the 1st quadrant
Converse: If the coordinates are positive, then the point is in the first quadrant
In which quadrant is the point (-5, 6)
The point (1,3) is located in the first quadrant.

Converse: If the coordinates are positive, then the point is in the first quadrant
If the signs of the Cartesian coordinates are: (+, +) => first quadrant (-, +) => second quadrant (-, -) => third quadrant (+, -) => fourth quadrant. If one of the coordinates is 0 then the point is on an axis and NOT in a quadrant. If both coordinates are 0 then the point is at the origin. If the location of the point is given in polar coordinates, then you only need the angle. Suppose the principal angle is Φ, then 0 < Φ < 90 degrees => first quadrant 90 < Φ < 180 => second quadrant 180 < Φ < 270 => third quadrant 270 < Φ < 360 => fourth quadrant. Again, if the angle is 90, 180 etc degrees, the point is on an axis. If the magnitude is 0 then the point is at the origin.
