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).

How do you find the slope of the line that passes through 2 points?
Assume your points are (x1, y1) and (x2, y2). The slope of a line is its rise (the change in y-coordinates) over its run (the change in x-coordinates). So to find the slope of the line, you substitute the correct values into the formula (y2 - y1) / (x2 - x1).
What is vertical change?
On a graph, the distance above and below the x-axis is given by the y-coordinate. Each point has a distinct location on the graph given by (x,y) where x represents the horizontal placement of the point and y represents the vertical placement. As you move from one point to another on the graph, your coordinates change. For example as you go from the point (2, 5) to (6, 15) your x-values went from 2 to 6, meaning they changed by 4 units (the difference in the x-coordinates). The x-values are your horizontal placements, so the horizontal change was 4 units. The y-values, are your vertical placements. They went from 5 to 15, a difference of 10 units, so the Vertical Change is 10 units. Put simply, the vertical change is the difference in the y-coordinates.
If abc is reflected across the y-axis what are the coordinates of a?
If point ( a ) has coordinates ((x, y)), its reflection across the y-axis would change the x-coordinate to its negative, resulting in the new coordinates ((-x, y)). Therefore, the coordinates of point ( a ) after reflection across the y-axis would be ((-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 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).
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 is a reflection as a math term?
A reflection is when a shape flips completely over. The coordinates of the shape will opposite as well. The reflection can change depending what you are flipping it over.

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.
Triangle 2 is a reflection over the x-axis of triangle 1. Point A of triangle 1 is (-6 -1). What would be the coordinates of point A'?
To find the coordinates of point A' of triangle 2, which is a reflection of point A over the x-axis, you need to change the sign of the y-coordinate while keeping the x-coordinate the same. Since point A is at (-6, -1), the reflected point A' will have coordinates (-6, 1).
Does reflection change in orientation?
Yes, reflection changes the orientation of an object by flipping it across an axis, such as a line, without changing its shape or size. The object appears as a mirror image of its original position.
Triangle 2 is a reflection over the x-axis of triangle 1. Point C of triangle 1 is (-5 -6). What would be the coordinates of point C'?
To find the coordinates of point C' after reflecting point C over the x-axis, you need to change the sign of the y-coordinate while keeping the x-coordinate the same. Given point C of triangle 1 is (-5, -6), the coordinates of point C' after reflection would be (-5, 6).
Does a reflection change the orientation of a shape?
Well, honey, a reflection doesn't change the orientation of a shape. It simply flips it over a line, like checking yourself out in a mirror. So, if you're looking for a quick fix to change things up, a reflection is your go-to move.
