Question

1) where does a point lie in a Cartesian plane .A(3,-4),B(-5,3),C(-3,-4)D(5,7),E(0,3),F(-4,0),G(0,-5),H(7,0),O(0,0)​

Answer 1

The Cartesian plane is divided into 4 quadrants

(i) 1st quadrant = (positive, positive)

(ii) 2nd quadrant = ( negative , positive )

(iii) 3rd quadrant = ( negative , negative )

(iv) 4th quadrant = ( positive, negative )

Using this we can identify any points quadrant.

___________________________________€

1) A(3,-4) = 4th quadrant

2) B (-5,3) = 2nd quadrant

3) C (-3,-4) = 3rd quadrant

4) D (5,7) = 1st quadrant

5) E ( 0,3) = on y axis in 1st quadrant

6) F (-4,0) = on x axis in 2nd quadrant

7) G ( 0,-5) = on y axis in 4th quadrant

8) H (7,0) = on x axis in 1st quadrant

9) O(0,0) = origin
