When you reflect a figure across the x axis do the x-coordinates change or remain the same?
When you reflect a figure across the x-axis, the x-coordinates of the points remain the same, while the y-coordinates change sign. This means that if a point is at (x, y), its reflection across the x-axis will be at (x, -y).
Which choice shows the image of triangle LMN after a translation of 5 units to the left followed by a reflection over the line y x?
To determine the image of triangle LMN after a translation of 5 units to the left and a reflection over the line y = x, first, translate each vertex of the triangle 5 units left. For example, if point L is at (x, y), it will move to (x - 5, y). Then, reflect the new coordinates over the line y = x, which involves swapping the x and y coordinates for each vertex. The final coordinates will represent the new position of triangle LMN after both transformations.
Will the distance between a point with a whole number coordinates and its reflection over the X axis always be even?
Yes, it will.
What is the pair of numbers used to determine the postition of a point on a graph?
The x and y coordinates.
What kind of correspondence there is between the points in the coordinate plane?
There are infinitely many possible correspondences between points in the coordinate plane. Some examples: Every point with coordinates (x+1, y) is one unit to the right of the point at (x, y). Every point with coordinates (x, y+1) is one unit up from the point at (x, y). Every point with coordinates (x, -y) is the reflection, in the y-axis of the point at (x, y).
How do you determine the coordinates of a point after a reflection in the x-axis?
The points after reflection will follow points equal but different direction, to the path followed before the reflection. So, if the line would cover 3.5 on the x and 5 on the y; it will reflect symmetrically giving you the formula to get your answer.
DEF has coordinates P=?
a reflection across the line y=x
What does Rx0 mean?
If it is Rx=0, it means you are reflecting your set of coordinates and reflect it across the x-axis when x=0. So it pretty much is saying reflect it over the y-axi
How does reflection across the y-axis change the coordinates of the orignal point?
y' = y, x' = -x.
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).
When you reflect a figure across the x axis do the x-coordinates change or remain the same?
When you reflect a figure across the x-axis, the x-coordinates of the points remain the same, while the y-coordinates change sign. This means that if a point is at (x, y), its reflection across the x-axis will be at (x, -y).

When ABC is reflected across x 1 and y -3. What are the coordinates of the reflection image of A after both reflections?
The answer will depend on the original coordinates of A: these have not been provided so neither has an answer.
Will the distance between a point with a whole number coordinates and its reflection over the X axis always be even?
Yes, it will.
Will the distance between a point with whole number coordinates and its reflection over the x-axis always be an even number?
Yes. Suppose the point is P = (x, y). Its reflection, in the x-axis is Q = (x, -y) and then |PQ| = 2y.
What are the coordinates of D' if quadrilateral ABCD is reflected about the x-axis?
In order to answer that, I need to know the position of ABCD with respect tothe x-axis before the reflection process begins.But wait! What light through yonder window breaks ? ! On second thought, maybe I don't.If D is the point (x, y) before the reflection, then D' is the point (x, -y) after it.
How do you determine where to mark a point on the graph?
At the given coordinates where the x and y values intersect
