Question
Which of the following points lie on the y-axis?a. (0, 3) b. (–3, 0)c. (–5, –1) d. (4, –3)Q.2 What is the ordinate of the point (3, –5)?a. 3 b. – 5c. – 2 d. 0Q.3 The equation of x-axis isa. x = 0 b. y = 0c. x = a d. y = aQ.4 In which of the following quadrants does the point P(–3, –2) lie?a. I b. IIc. III d. IVSection BFill in the blanks.Q.5 The x co-ordinate of a point is its distance from the_______________.Q.6 The co-ordinates of any point on the y axis are of the form.___________________.Q.7 A point which lies on both the axes is______________.Q.8 The point (–2, 1) lies in the _____________ quadrant
Solution
Q.1 The point that lies on the y-axis is a. (0, 3). This is because any point on the y-axis has an x-coordinate of 0.
Q.2 The ordinate of the point (3, –5) is b. -5. The ordinate of a point refers to its y-coordinate.
Q.3 The equation of the x-axis is b. y = 0. This is because all points on the x-axis have a y-coordinate of 0.
Q.4 The point P(–3, –2) lies in the c. III quadrant. This is because in the III quadrant, both x and y coordinates are negative.
Section B
Q.5 The x co-ordinate of a point is its distance from the y-axis.
Q.6 The co-ordinates of any point on the y axis are of the form (0, y).
Q.7 A point which lies on both the axes is the origin (0,0).
Q.8 The point (–2, 1) lies in the II quadrant. This is because in the II quadrant, the x-coordinate is negative and the y-coordinate is positive.
