Plotting a Point
Trending Questions
Point (-3, 5 ) lies in the
A) First quadrant
B) Second quadrant
C) Third quadrant
D) Fourth quadrant
Thinking process
(i) Firstly, check the sign of each coordinate of a point.
(ii) If both coordinates x and y has the same positive sign, i.e(+ .+), then the point lies in the first quadrant.
(iii) If x coordinate has the negative sign and y-coordinate has positive sign i.e( -, +), then the point lies in the second quadrant.
(iv) if both coordinate x and y has negative sign i.e ( -, -) then the point lies in the third quadrant.
(v) if x coordinate has a positive sign and y-coordinate has negative sign i.e (+, -), then the point lies in the fourth quadrant.

How do you find out the mirror image of a point?
The distance of any point from the x-axis is called the x-coordinate. State whether the statement is true (T) or false (F).
- True
- False
In which quadrant or on which axis do the point lie?

Points (-4, 0) and (7, 0) lie
in second quadrant
in first quadrant
on x-axis
y-axis
Point ( 0, -7) lies
Thinking process
(i) Firstly, check whether any coordinate of the given point is zero or not.
(a) If x-coordinate is zero and y-coordinate is non-zero, then the point lies on the y-axis.
(b) If y-coordinate is zero and x-coordinate is non-zero, then the point lies on the x-axis.
(c) If x-coordinate and y-coordinate are zero, the point lies on the origin ( or on both the axes.)
(ii) If none of the coordinates is zero, then the point lies in any one of the four quadrants.
A) On the x-axis
B) In the second quadrant
C) On the y-axis
D) In the fourth quadrant
