Question

plot three points A, B and C which have same abscissa 4 but lie
in 1 and 4 quadrants and on x-axis respectively Also, plot mirror
image of A in y-axis

Answer : We know

Abscissa : The horizontal ( " x " ) value in a pair of
coordinates ( x , y ) How far along the point is
from y - axis

And given : Three A ,B and C points , As abscissa 4 but lie in 1
and 4 quadrant and on x axis respectively

So, we can write A ( 4 , 3 ) ( That comes in first quadrant ) ( As
we know in first quadrant ( + , + )

B ( 4 , - 5 ) ( That comes on fourth quadrant ) ( As we know in
fourth quadrant ( + , - )

And

C ( 4 , 0 ) ( That lie on x - axis )( As we know when a
point on x axis its ordinate value is zero )

And we know mirror image of a point in y - axis change (
x , y ) to ( - x , y )

So, Mirror image of A in y axis gives coordinate A' ( - 4
, 3 ) , We plot these points As :

plot three points A, B and C which have same abscissa 4 but lie in 1 and 4 quadrants and on x-axis respectively .Also, plot mirror image of A in y-axis.
