Answer

We know that,

Abscissa is the x-coordinate and ordinate is the y-coordinate of a point.

(i) The coordinate of the point whose abscissa is 3 and ordinate is -4 is (3, -4).

(ii) The coordinate of the point whose abscissa is 32-\dfrac{3}{2} and ordinate is 5 is (32,5)\Big(-\dfrac{3}{2}, 5).

(iii) The coordinate of the point whose whose abscissa is 123-1\dfrac{2}{3} and ordinate 214-2\dfrac{1}{4} is (123,214)\Big(-1\dfrac{2}{3}, -2\dfrac{1}{4}\Big).

(iv) The coordinate of the point whose ordinate is 5 and abscissa is -2 is (-2, 5).

(v) Since, point lies on x-axis. So, ordinate of point will be = 0.

The coordinate of the point whose abscissa is -2 and lies on x-axis is (-2,0).

(vi) Since, point lies on y-axis. So, abscissa of point will be = 0.

The coordinate of the point whose ordinate is 32\dfrac{3}{2} and lies on y-axis is (0,32)\Big(0, \dfrac{3}{2}\Big).
