Q. 1

# Let us plot the following points on the graph paper and write their positions (on the axes or in quadrant).

(i) (3, 0) (ii) (0, 8)

(iii) (–5, 0) (iv) (0, –6)

(v) (6, 4) (vi) (–7, 4)

(vii) (9, –9) (viii) (–4, –5)

Answer :

__Key Points__ -

● (x,y) = (abscissa, ordinate)

● Parallel lines ⇒ No Solution.

● One Intersection point ⇒ only one Solution

● Infinite Intersection point ⇒ Infinite solutions

X coordinate is called abscissa and y coordinate is called ordinate.

To plot all these points, we need to find the value of abscissa on the x axis and ordinate on y

axis.

From the graph, we can clearly see the position of points as :

(i) (3, 0): On X - axis

(ii) (0, 8): On Y - axis

(iii) (–5, 0): On X - axis

(iv) (0, –6): On Y - axis

(v) (6, 4): In First Quadrant

(vi) (–7, 4): In second Quadrant

(vii) (9, –9): In IV quadrant

(viii) (–4, –5): In third quadrant

Let us write the distances of the point (6, –8) from x - axis and y - axis.

West Bengal MathematicsThe distances of a point from x-axis in positive direction is 5 units and from y-axis in positive direction is 7 units. Let us write the co-ordinates of the point.

West Bengal Mathematics1 plot the following points on graph paper and write the points lie on the right or left side of the y-axis.

(5, –7), (–10, 10), (–8, –4), (4, 3), (–6, 2), (11, –3), (4, 0), (–4, 0)

West Bengal Mathematics1 plot the following points on graph paper and write the points lie above or below the x-axis.

(3, –2), (–4, 2), (4, 5), (–5, –5), (–2, 7), (7, –7), (0, 9), (0, –9)

West Bengal MathematicsLet us plot the following points on the graph paper and write their positions (on the axes or in quadrant).

West Bengal Mathematics1 plot the following points on graph paper and write their positions (In which quadrant or on which axis and in which direction).

(–11, –7), (0, 5), (9, 0), (–4, –4), (12, –9), (3, 13), (0, –6), (–5, 0),

West Bengal MathematicsLet us write the co-ordinates of any four points lying in each quadrant.

West Bengal MathematicsLet us write the co-ordinates of any four points lying on x-axis.

West Bengal MathematicsOn the graph paper, let us draw XOX’ & YOY’ the two perpendicular axes and plot any 5 points lying in the 3^{rd} quadrant.

Let us write the co-ordinates of any four points lying on y-axis.
