Study the given co-ordinates system carefully and fill in the blanks .

(i) The sum of abscissa of point A and ordinate of point E is ______.
(ii) The coordinates of point D are _____.
(iii) The difference between the ordinates of point B and point C is ______.

Options

A. `{:("(i)","(ii)","(iii)"),(1,"(2,-4)","-1"):}`
B. `{:("(i)","(ii)","(iii)"),(-1,"(-2,-4)","-1"):}`
C. `{:("(i)","(ii)","(iii)"),(2,"(4,-2)","2"):}`
D. `{:("(i)","(ii)","(iii)"),(-2,"(-4,-2)","3"):}`

Answer

B

Explanation

`A -=(1,2),B -= (-4,3),C-=(5,4),D -= (-2,-4), E -= (4,-2)`
(i) Abscissa of A = 1
Ordinate of E = - 2
`therefore` Required sum = 1-2 = - 1
(ii) Coordinates of `D -= (-2,-4)`
(iii) Ordinate of B = 3
Ordinate of C = 4
`therefore ` Required difference `= 3 - 4 = - 1`
