Question 95
The point R(a,b) is first reflected in origin to R1 and R1 is reflected in X-axis to (-5,1). The co-ordinates of point R are?
Solution
R(a,b) after reflection at the origin = (-a,-b)
Reflection of point (-a,-b) in the x-axis is (-a,b)
According to ques,
=> $$(-a,b) = (-5,1)$$
=> $$-a = -5$$ and $$b = 1$$
$$\therefore$$ Coordinates of Point R = (5,1)
=> Ans - (D)
