Question

write down the co-ordinate of the image of the point 3, - 2 when reflrctrd in the x-axis reflected in the y axis third reflection in the x-axis followed by reflection in the y-axis reflected in the origin

Answer 1

(i) The image of the point (3, 4) in the x-axis is the point (3, -4).

(ii) The image of the point (-3, -4) in the x-axis is the point (-3, -(-4)) i.e., (-3, 4).

(iii) The reflection of the point (5, -7) in the x-axis = (5, 7) i.e., Mx (5, -7) = (5, 7)

(iv) The reflection of the point (9, 0) in the x-axis is the point itself, therefore, the point (9, 0) is invariant with respect to x-axis.

(v) The reflection of the point (-a, -b) in the x-axis = (-a, b) i.e., Mx (-a, -b) = (-a, b)
