Question

1. R(2,7) Across the y-axis Across the x-axis:​

Answer 1

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

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 )

Answer 2

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
