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 and ordinate is 5 is . (iii) The coordinate of the point whose whose abscissa is and ordinate is . (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 and lies on y-axis is .
