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).
How do you rotate 180 degrees counter clockwise about origin?
To rotate a point 180 degrees counterclockwise about the origin, you can simply change the signs of both the x and y coordinates of the point. For example, if the original point is (x, y), after the rotation, the new coordinates will be (-x, -y). This effectively reflects the point across the origin.
What is meant by slope in coordinate geometry?
Rise over run, generally change in y-coordinates divided by change in x-coordinates.
What is reflecting points across the x and y axis?
Reflecting points across the x-axis involves flipping them vertically, meaning that if a point has coordinates (x, y), its reflection will be at (x, -y). Conversely, reflecting points across the y-axis involves flipping them horizontally, resulting in the coordinates changing from (x, y) to (-x, y). These transformations change the position of points in a Cartesian coordinate system while preserving their distance from the axes.

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).
What is the rule for a reflection across the origin?
To reflect a point across the origin, you simply change the sign of both the x- and y-coordinates of the point. This transformation involves multiplying the coordinates by -1.
How do you rotate 180 degrees counter clockwise about origin?
To rotate a point 180 degrees counterclockwise about the origin, you can simply change the signs of both the x and y coordinates of the point. For example, if the original point is (x, y), after the rotation, the new coordinates will be (-x, -y). This effectively reflects the point across the origin.
How does reflection across the y-axis change the coordinates of the orignal point?
y' = y, x' = -x.
How doe the reflection across the x axis change the coordinates pf a point?
If your points are (p,f), they become (p,-f).
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 meant by slope in coordinate geometry?
Rise over run, generally change in y-coordinates divided by change in x-coordinates.
When reflecting a figure in the x-axis will you change all of the figures X coordinates or the y coordinates?
The y-coordinates.The y-coordinates.The y-coordinates.The y-coordinates.
What are Ireland's coordinates?
Ireland's geographic coordinates are 53 00 N, 8 00 W. Coordinates change over the years as the earth moves.

How does the proportional change in the dimensions affect the area of a polygon?
Change in area = (change in sides)2
