Question 5

The point Q(a,b) is first reflected in y axis to Q1 and Q1 is reflected in x axis to (5,3). The coordinates of point Q are

Solution

Q(a,b) after reflection in the y-axis = (-a,b)

Reflection of point (-a,b) in the x-axis is (-a,-b)

According to ques,

=> $$(-a,-b) = (5,3)$$

=> $$a = -5$$ and $$b = -3$$

$$\therefore$$ Coordinates of Point Q = (-5,-3)

=> Ans - (D)
