If P=(3,4), find:
R y-axis (P)
Please help!!

Answer:
(-3,4)
Step-by-step explanation:
That means to reflect the point across the y-axis... If you draw (3,4) on the coordinate plane you should see (-3,4) is the reflection across the y-axis from that point.
Answer:
P' = (- 3, 4 )
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), hence
P(3, 4 ) → P'(- 3, 4 )
