Question

Plot a point A(2, -5)on the Cartesian plane Now, change the sign of
its ordinate and call it B Plot B now, plot reflections of A and B
in y-axis

Dear student
We have,
Point A(2,-5)
and B(2,5)

Rules to find the reflection of a point in the y-axis:

(i) Change the sign of abscissa i e , x-coordinate

(ii) Retain the ordinate i e , y-coordinate
Reflection of A is A'(-2,-5)
Reflection of B is B'(-2,5)

Plot a point A(2, -5)on the Cartesian plane. Now, change the sign of its ordinate and call it B. Plot B now, plot reflections of A and B in y-axis.
