Exercise- 12A
Que-1: Draw co-ordinate axes and represent the following points :
(i) A(2,4) (ii) B(-1,3) (iii) C(4,-3) (iv) D(-3,-4) (v) E(0,6) (vi) F(-2,0)
Sol:
Que-2: On which axis does the following point lie?
(i) P(3,0) (ii) Q(0,4) (iii) R(-2,0) (iv) S(0,-3)
Sol: (i) P(3,0)
Its y = 0
P lies on x-axis
(ii) Q(0,4)
Its x = 0
Q lies on y-axis
(iii) R(-2,0)
Its y = 0
R lies on x-axis
(iv) S(0,-3)
Its x = 0
S lies on y-axis.
Que-3: Find the distance of each of the following points from x-axis and y-axis :
(i) A(7,4) (ii) B(3,-5) (iii) C(-4,-2) (iv) D(-3,6)
Sol: (i) Point A is 4 units from x-axis and 7 units from y-axis
(ii) Point B is 5 unit from x-axis and 3 units from y-axis
(iii) Point C is 2 unit from x-axis and 4 unit from y-axis
(iv) Point D is 6 unit from x-axis and 3 unit from y-axis.
Que-4: A point lie on x-axis at a distance of 4 units from y-axis. What are the co-ordinates of this points ?
Sol: The point is on x-axis
Its y = 0
The point is at a distance of 4 units from y-axis
Its x = 4
Hence, co-ordinate of the point will be (4,0).
Que-5: A point lies on y-axis at a distance of 5 units from x-axis. What are the co-ordinates of this points ?
Sol: The point is on y-axis
Its x = 0
The point is 5 units from x-axis
Its y = 5
Hence, co-ordinate of the point will be (0,5).
Que-6: What do you mean by the lines :
(i) x = 0 ? (ii) x = 4 ? (iii) y = 0 ? (iv) y = 4 ? (v) x = -3 ? (vi) y = -2 ?
Sol: (i) x = 0
It is y-axis
(ii) x = 4
It is a line parallel to y-axis at a distance of 4 units to right of it.
(iii) y = 0
It is x-axis
(iv) y = 4
It is a line parallel to x-axis at a distance of 4 units above it.
(v) x = -3
It is a line parallel toy-axis at a distance of 3 units to left of it.
(vi) y = -2
It is a line parallel to x-axis at a distance of 2 units below x-axis.
