Telangana SCERT Class 9 Math Solution Chapter 5 Co-Ordinate Geometry Exercise 5.2

Telangana SCERT Solution Class IX (9) Math Chapter 5 Co-Ordinate Geometry Exercise 5.2

(1) (i) (-2, 3) lies on 2nd Quadrant

(ii) (5, -3) lies on the 4th quadrant

(iii) (4, 2) lies on the first Quadrant

(iv) (-7, -6) lies on the 3rd Quadrant

(v) (0, 8) lies on the Y axis

(vi) (3, 0) lies on the X – axis

(vii) (-4, 0) lies on the X –axis

(viii) (0, – 6) lies on the Y axis

(2)

(i) abscissa = 4 (X – coordinate)

Ordinate, -8 (Y – coordinate)

(ii) Abscissa = – 5

Ordinate = 3

(iii)  Abscissa = 0

Ordinate = 0

(iv) Abscissa = 5

Ordinate = 0

(v) Abscissa = 0

Ordinate = -8

(3) (i) (-5, -8) does not lie on any axes.

(ii) (0. 13) lies on the y axis.

(iii) (4, -2) does not lie on any axis.

(iv) (-2, 0) lies on the x-axis.

(v) (0, -8) lies on the y axis.

(vi) (7, 0) lies on the x-axis.

(4)

(i)  The ordinary of L based on the graph is -7

(ii) The ordinate of Q based on the graph is 7

(iii) (-2m -2) is donated by R

(iv) (5, -4) is donated by P

(v) Abscissa of N is 4

(vi) Abscissa 7 M is -3

(5)

(i) False, horizontal axis is called x-axis

(ii) True

(iii) False, origin is (0, 0) of any X – Y plane

(iv) False, (2, – 3) Lies of the 4th Quadrant

(v) False, (-5, -8) Lies on the 3rd Quadrant

(vi) False (-x, -y) lies on the 3rd Quadrant

(6)

(i) From the following pairs plotted on the graph, we observe that all the pairs plotted lies on the X axis of the X – Y plane. All the ordinates of the points are 0. Only the origin (0, 0) lies on both axes.

(ii) From the following pairs plotted on the graph we observe that all the pairs plotted lies on the Y – Axis of the X – Y plane except the origin (0, 0) which lies on both axes. Hence, All the Abscissa are 0.
