Question

The reflection of a point (-2,5) with respect to Y-axis is : (a) (2,-5) (b) (-2, 5) (c) (2)-5) (d) (2,5)​

Answer 1

Answer:

(d) (2,5)

Step-by-step explanation:

Given: Point (-2,5)

To find: Reflection with respect to y-axis.

Solution:

We know that $\bold{(R)_y(x,y)=(-x,y)}$.

=> $\bold{(R)_y(-2,5)=(2,5)}$

Reflection of P(x,y) in x-axis is P'(x,-y).

Reflection of P(x,y) in y-axis is P'(-x,y).

Reflection of P(x,y) in the origin is P'(-x,-y)

Answer 2

Answer:

(d) (2,5)

Step-by-step explanation:

Given: Point (-2,5)

To find: Reflection with respect to y-axis.

Solution: We know that (R)y(x,y) = (-x,y)

=> (R)y(-2,5) = (2,5)

Learn more:

Reflection of P(x,y) in x-axis is P'(x,-y).

Reflection of P(x,y) in y-axis is P'(-x,y).

Reflection of P(x,y) in the origin is P'(-x,-y)
