Write down the coordinates of each of the points P, Q, S and T, as shown in the figure given on next page.

Explanation

Draw perpendicular PL, QM, RN SU.TV on the x-axis
(i) The distance of P from the y-axis = `OL = 2` units.
The distance of P from the x-axis = LP = 4 units.
Hence, the coordinates of P are (2, 4)
(ii) The distance of Q from the y-axis = OM = 4 units
The distance of Q from the x-axis = OM = 2units.
Hence, the coordinates of Q are (4, 2)
(iii) The distance of R from they y-axis = ON = `-2` units
The distance of R from the x-axis = NR = 3 units.
Hence, the coordinates of R are `(-2, 3)`.
(iv) The distance of S from the y-axis = OU = 5 units.
The distance of S from the x-axis = US = `-3` units.
Hence, the coordinates of S are `(5, -3)`.
(v) The distance of T from the y-axis `= OV = -4` units.
The distance of T from the x-axis `= VT = -1` unit.
Hence, the coordinates of T are `(-4, -1)`
