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

$\begin{array}{ccc}& ColumnA& ColumnB\\ a& \text{(0,5)}& \text{(i)Y-coordinate is 2}\times \left(\text{X-coordinate}\right)+1.\\ b& \text{(2,3)}& \text{(ii)Coordinates of origin.}\\ c& \text{(4,8)}& \text{(iii) Only Y-coordinate is zero.}\\ d& \text{(3,7)}& \text{(iv) The distance from X-axis is 5.}\\ e& \text{(0,0)}& \text{(v) Y-coordinate is double of X-coordinate.}\\ f& \text{(5,0)}& \text{(vi) The distance from Y-axis is 2}\end{array}$

Answer 1

(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 $\times$ (X-coordinate)+1
(e) (0,0) are the coordinates of origin.
(f) In the point (5,0), the Y-coordinate is zero.
Hence, $\left(a\right)\to iv,\left(b\right)\to vi,\left(c\right)\to v,\left(d\right)\to i,\left(e\right)\to ii,\left(f\right)\to iii.$
