Class 9 RD SHARMA Solutions Maths Chapter 8 - Co-ordinate Geometry
Co-ordinate Geometry Exercise Ex. 8.1
Solution 1
The graph of the given points are:
Solution 2
The coordinates of the given points are A(3,1), B(6,0), C(0,6), D(-3,0), E(-4,3), F(-2,-4), G(0,-5), H(3,-6), P(7,-3) and Q(7,6)
Co-ordinate Geometry Exercise 8.7
Solution 1
The point of intersection of co-ordinate axes i.e. X-axis and Y-axis is (0, 0), which is called origin.
Hence, correct option is (d).
Solution 2
Solution 3
Solution 4
Abscissa is = 2 (positive intercept on X-axis)
and ordinate = -5 (negative intercept on Y-axis)
so X-value is positive and Y-value is negative, i.e. Fourth Quadrant.
Hence, correct option is (d).
Solution 5
In (-4, 0) and (7, 0 ),
measure of ordinate = 0
That means, intercept on Y-axis = 0
So, points lies on X-axis.
Hence, correct option is (a).
Solution 6
On X- axis, all points have their Y- intercept = 0
So their ordinate = 0
Hence, correct option is (a).
Solution 7
Every point on Y-axis have X-intercept = 0
Thus, their abscissa = 0
Hence, correct option is (a).
Solution 8
Abscissa = Intercept on X-axis
If intercept on X-axis is positive, means First and Fourth quadrant.
Hence, correct option is (d).
Solution 9
Solution 10
Let two points be (a, b) and (a, c).
If abscissa is same = a
and ordinate is different then all such points will lie on a line parallel to Y- axis because value of X-intercept
i.e. abscissa is fixed.
Hence, correct option is (c).
