Question

Point P(a, b) is reflected in the x-axis to P'(5, – 2).

(i) Write the values of a and b.

(ii) P" is the image of P when reflected in the y-axis. Write the coordinates of

P".

(iii) Name a single transformation that maps P' to P".​

Answer 1

Answer:

P(a, b) => x axis => P'(a, - b)

therefore P' (5, -2) => P(5, 2)

P (a, b) => y axis => P"(-a , b)

P(5, 2) => y axis => P" ( -5, 2)

P (a, b) => P' => P" => P(-a, -b) => about origin

P (5, 2 ) => origin => P" => (-5, -2)
