Abscissa and ordinate of all the points on the x-axis will be

• Any number, Zero

• Zero, Any Number

• Any number, Any number

• Zero, Zero

Answer explanation

Abscissa of all the points on the X-axis means any number on x axis. Ordinate of all points on the X-axis is zero. Because ordinate (or y-coordinate) of a point is perpendicular distance of this point from the X-axis measured along the Y-axis. If a point lies on X- axis, then the perpendicular distance of that point from X- axis will be zero, so the ordinate will be zero.

Point (4, -5) lies in the

• 1st Quadrant

• 2nd Quadrant

• 3rd Quadrant

• 4th Quadrant

Answer explanation

(i) Firstly, check the sign of each coordinate of a point. (ii) If both coordinates x and y has same positive sign i.e., (+, +), then the point lies in first quadrant. (iii) If x-coordinate has negative sign and y-coordinate has positive sign i.e., (-, +), then the point lies in second quadrant. (iv) If both coordinate x and y has negative sign i.e, (-, -), then the point lies in third quadrant. (v) If x-coordinate has positive sign and y-coordinate has negative sign i.e., (+, -), then the point lies in fourth quadrant In this condition, the point (4, -5), x-coordinate is positive and y-coordinate is negative. So, the point lies in the fourth quadrant.

Coordinates of a point on the x-axis are of the form ___and the points on y-axis are of the form ____

• (0, y) & (0, x)

• (y, x) & (x, y)

• (x, 0) & (0, y)

• (x, 0) & (y, 0)

Answer explanation

Coordinates of a point on the x-axis are of the form (x, 0) and that of the point on the y-axis is of the form (0, y).
