The reflection of a point across the y-axis involves changing the sign of the x-coordinate while keeping the y-coordinate the same. In this case, the point (-1, -5) will reflect to (1, -5) across the y-axis. This is because the x-coordinate changes from -1 to 1, while the y-coordinate remains -5.

What is the rule for a reflection across the x-axis?
For a reflection across the x axis, both the slope and the y intercept would have the same magnitude but the opposite sign.
What happens when a function reflects across the x-axis?
Nothing really happens. y is swapped for -y. But that is what reflection means and so is a tautological answer!
What is a horizontal reflection?
a horizontal reflection is a reflection of the y axis. i.e (-fx)
What is the rule for a reflection across the y-axis followed by a translation 1 unit to the right and 4 units up?
(x' , y') = (-x + 1 , y + 4)
If the y-axis is the reflecting line and A is -1 2 its reflection image is A' equals?
A' = (-1, -2)
How does a reflection across the y axis change the coordinates of a point?
Reflection across the y-axis changes the sign of the x - coordinate only, that is, (x, y) becomes (-x, y).
Which graph shows a reflection across the x-axis?
y = -f(x) is a reflection of y = f(x) in the x axis.
What is the reflection image of U across the y axis?
c

How does reflection across the y-axis change the coordinates of the orignal point?
y' = y, x' = -x.
What single transformation is equivalant to a reflection in the y axis followed by a reflection in the x axis followed by another reflection in the y axis?
reflection in the x-axis
What is the reflection image of 5 -3 across the y axis?
The y-axis is the symmetry line, so that (5, -3) and (-5, -3) are symmetric points.
Is the composition of a reflection across the x and y axis similar to a 180 degree rotation about the origin?
yup.

A' = (-1, -2)
