$\setlength{\unitlength}{2.5mm}\begin{picture}(10,10)\multiput(0,0)(2,0){21}{\line(0,1){40}}\multiput(0,0)(0,2){21}{\line(1,0){40}}\linethickness{0.45mm}\put(20,20){\vector(2,0){18}}\put(20,20){\vector(-2,0){18}}\put(20,20){\vector(0,2){18}}\put(20,20){\vector(0,-2){18}}\multiput(19.35,6)(0,2){15}{\line(1,0){1.3}}\multiput(6,19.35)(2,0){15}{\line(0,1){1.3}}\put(20,20){\circle*{1}}\put(22,22){\sf O(0, 0)}\put(24,30){\circle*{1.1}}\put(24,30){\circle{2}}\put(15,27.5){\sf (0, 4)}\put(14,20){\circle*{1.1}}\put(14,20){\circle{2}}\put(13,17){\sf (-3, 0)}\put(20,28){\circle*{1.1}}\put(20,28){\circle{2}}\put(22,32){\sf (2, 5)}\put(21,37){\sf Y}\put(21,2){\sf Y'}\put(2,21){\sf X'}\put(37,21){\sf X}\end{picture}$

Here,

(-3, 0) lies in Quadrant II.

(0,4) lies in Quadrant I.

(2,5) lies in Quadrant I.

★ The Cartesian plane is divided into four quadrants.

⠀⠀⠀⠀⠀⠀⠀

In Quadrant I, both the x - and y-coordinates are positive.

In Quadrant II, the x-coordinate is negative, but the y-coordinate is positive.

In Quadrant III, both are negative.

In Quadrant IV, x is positive, but y is negative.
