Answer:

Point  R(2,7) has coordinates of (x, y), where x = 2 and y = 7, so

  • Across the y-axis = 7
  • Across the x-axis = 2

Answer:

(- 2, 7 ) and (2, - 7 )

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

(2, 7 ) → (- 2, 7 )

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

(2, 7 ) → (2, - 7 )
