Reflection across the x-axis?
In transformations a reflection across the x axis produces a mirror image
What is the reflection image of U across the y axis?
c
What is the reflection of (-2.5 2.75) across the axis?
(2.5,-2.75)
How can you reflect figures in the x-axis and y-axis?
For reflection in the x-axis, change the sign of the y-coordinate of every point.For reflection in the y-axis, change the sign of the x-coordinate of every point.
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
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).
What is the reflection of (-1-5) across y axis?
It is: (1, -5) reflection across the y axis
Reflection across the x-axis?
In transformations a reflection across the x axis produces a mirror image
How does reflection across the y-axis change the coordinates of the orignal point?
y' = y, x' = -x.
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.
Which graph shows a reflection across the x-axis?
y = -f(x) is a reflection of y = f(x) in the x axis.
How doe the reflection across the x axis change the coordinates pf a point?
If your points are (p,f), they become (p,-f).
What does reflection over the y-axis mean?
Example: if you have a point with the coordinates (2,4), a reflection over the y-axis will result in the point with coordinates (-2,4).
What is the reflection image of U across the y axis?
c
What is the reflection of (-2.5 2.75) across the axis?
(2.5,-2.75)
How do you find the reflection of a point that is reflected over the x- axis and then over the x- axis?
It will be where it was, to start with.
What is the difference between rotation and reflection in graphic design?
Rotation is a transformation that spins an object on a specific point. In Adobe Illustrator, an object's default rotation point is its centre.Reflection is a transformation that flips an object over and across a specific axis. In Adobe Illustrator, an object's default reflection axis runs vertically through its centre.
