Question 35
Match the ordinates of the points given in Column A with the items mentioned in Column B.

   Column A   Column Ba        (0,5)(i)Y-coordinate is 2×(X-coordinate)+1.b        (2,3)(ii)Coordinates of origin.c        (4,8)(iii) Only Y-coordinate is zero.d        (3,7)(iv) The distance from X-axis is 5.e        (0,0)(v) Y-coordinate is double of X-coordinate.f        (5,0)(vi) The distance from Y-axis is 2
 


Solution

(a) In the pair (0,5), the second number also known as ordinate represents the distance from X-axis, i.e. 5.
(b) In the pair (2,3), 2 is the first number, also known as abscissa represents the distance from Y-axis that is 2.
(c) We have the coordinates (4,8). Clearly, Y-coordinate is double of X-coordinate.
(d) We have the coordinate (3,7), where X-coordinate=3 and Y-coordinate=7. Evidently, Y-coordinate =2 × (X-coordinate)+1
(e) (0,0) are the coordinates of origin.
(f) In the point (5,0), the Y-coordinate is zero.
Hence, (a)iv, (b)vi, (c)v, (d)i, (e)ii, (f)iii.
