∙ 13y agoBasically you write a series of if statements, to cover the different cases. For example, in Java, something like this:
...
if (x = 0)
System.out.println("On y-axis")
else if (y = 0)
System.out.println("On x-axis")
else if (x > 0)
if (y > 0)
System.out.println("First quadrant")
else

∙ 13y agoThe point (1,3) is located 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.

If you mean the point (7, 9) then it is in the 1st quadrant
In which quadrant is the point (-5, 6)
The point (1,3) is located in the first quadrant.
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.
The point (2, 3) is located in the 1st quadrant

In the 1st 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.
Converse: If the coordinates are positive, then the point is in the first quadrant

In general, any point that falls on the axes, is not considered to be in any quadrant. This answer is used in most HS texts since it is simple and "works." However, you can define things so that a point with a single zero coordinate will either (1) be common to the two adjacent quadrants, or (2) be part of one and only one quadrant. Here is how to do the second choice. associate the positive x-axis with quadrant I, the positive y-axis with quadrant II, the negative x-axis with quadrant III, and the negative y-axis with quadrant IV. Then what do we do about (0,0)? This is why the first answer works and if most often used. The other possibilities are only mentioned so you can see they exists.
If you mean point (2, 5) then it is in the 1st quadrant on the Cartesian plane
