Which of the following are the signs of the coordinates of a point that lies in the third quadrant?
The signs of the point that lies in the third quadrant are (-,-).
The perpendicular distance of a point from x-axis 3 units and its perpendicular distance from the y-axis is 7 units. What are the coordinates of this point if it lies in the fourth quadrant?
The signs of a point that lies in the fourth quadrant are (+,-). Therefore, its coordinates are (7,-3).
The perpendicular distance of a point from x-axis 5 units and its perpendicular distance from the y-axis is 1 unit. What are the coordinates of this point if it lies in the first quadrant?
The signs of a point that lies in the first quadrant are (+,+). Therefore, its coordinates are (1,5).
The perpendicular distance of a point from x-axis 8 units and it lies on the negative side of y-axis. What are the coordinates of this point?
The y-coordinate of the point is negative. Therefore, the coordinates of the point are (0,-8).
Which figure is formed by joining the points A(0,0), B(7,0) and C(0,9)?
Plot the points on the graph paper and it will become a right angled triangle.
Which quadrilateral is formed by joining the points A(0,0), B(4,0), and C(4,4) and D(0,4)?
Plot the points on the graph paper and it will become a square of side length 4.
Which of the following represents (-3,-7)?
The point (-3,-7) lies in the third quadrant. It can be reached by going 3 units towards left and 7 units down from the origin.
Which of the following represents (5,-3)?
The point (5,-3) lies in the fourth quadrant. It can be reached by going 5 units towards right and 3 units down from the origin.
Which of the following represents (4,9)?
The point (4,9) lies in the first quadrant. It can be reached by going 4 units towards right and 9 units up from the origin.
What is the abscissa of any point y-axis?
As the point lies on the y-axis, its x-coordinate should be 0. Therefore, abscissa is 0.
Which of the following quadrants have points with negative abscissa?
Points having negative abscissa lie in second and third quadrant.
You move 7 units to the left from the origin and then moves 10 units up. At what point did you reach?
Moving 7 units to the left will make us reach at -7 on the x-axis and then moving up 10 units will make us reach the point (-7,10).
What is the minimum distance of the point (4,-7) from the x-axis?
The point (4,-7) lies 7 units below the x-axis. So the minimum distance of the point (4,-7) from the x-axis is 7 units.
What is the minimum distance of the point (-8,-10) from the y-axis?
The point (-8,-10) lies 8 units on the left of the y-axis. So the minimum distance of the point (-8,-10) from the y-axis is 8 units.
When two points A and B have same abscissa but different ordinates then they lie on:
Two points having same abscissa lie on a vertical line. As abscissa is not given as 0, therefore the points lie on a line parallel to y-axis.
Where does the mirror image of the point (-3,-1) about the x-axis lie?
Mirror image of (-3,-1) about x-axis will be at (-3,1).
Where does the mirror image of the point (7,-2) about the y-axis lie?
Mirror image of (7,-2) about y-axis will be at (-7,-2).
What is the distance between the points (10,-3) and (-1,-3)?
The points (10,-3) and (-1,-3) lie on a horizontal line. Distance between the points is 11 units.
What is the distance between the points (7,4) and (7,-5)?
The points (7,4) and (7,-5) lie on a vertical line. Distance between the points is 9 units.
What is the distance between the points (6,8) from the origin?
Plot the point on the graphing paper. Form a right triangle having perpendicular legs as 6 and 8. Use Pythagoras theorem to find the distance of the point (6,8) from the origin.
