Question

What are signs of abscissa and ordinate of the point in the second quadrant respectively? 2. What is the value of ordinate of any point lying on the x-axis? 3. What we called the point at which the two coordinate axes meet? 4. In which two quadrants the abscissa of a point is positive? 5. What is the perpendicular distance of the point (3,4) from the y-axis?

Answer 1

1. (-,+)

2. y=0

3. origin

4. 1 and 4 quadrants

5. 3

Answer 2

Step-by-step explanation:

1. (C) In second quadrant, X-axis is negative and Y-axis is positive. So, sign of abscissa of a point is negative and sign of ordinate of a point is positive.
2. zero From equation (1) and equation (2), we can observe that the y-coordinate of any point lying on the x-axis is equal to zero. Therefore, the ordinate of a point lying on. the x-axis is equal to zero.
3. It is called origin as all the measurement along the axes are taken from O as a reference point.
4. A coordinate is an ordered pair of numbers in which the first number is the abscissa i.e. the measurement along the X axis. So, the abscissa of the point is positive in the first and fourth quadrant.
5. We know that, abscissa or the x-coordinate of a point is its perpendicular distance from the Y-axis. So, perpendicular distance of the point P(3, 4)from Y-axis = Abscissa = 3.
