Reflection over the line y=x rule
Reflection over the line y=x rule-The rule for reflecting over the X axis is to negate the value of the ycoordinate of each point, but leave the xvalue the same For example , when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,4) · If a reflection in the line y = x occurs, then the rule for this reflection is/ a (x, y) in (y, x) b (x, y) in (y, x) c (x, y) in (x, y) d (x, y) in (x, y) Guest Apr 18, 17 1

Define the rule for reflecting across the y=x line Understand how to plug existing coordinates into these rules to obtain the reflection's points;A shape can be reflected in the line y = −x If point on a shape is reflected in the line y = −x both coordinates change sign (the coordinate becomes negative if it is positive and vice versa) the xcoordinate becomes the ycoordinate and the ycoordinate becomes the xcoordinateGraph functions using reflections about the xaxis and the yaxis Another transformation that can be applied to a function is a reflection over the x – or y axis A vertical reflection reflects a graph vertically across the x axis, while a horizontal reflection reflects a graph horizontally across the y
2401 · The rule for reflecting over the X axis is to negate the value of the ycoordinate of each point, but leave the xvalue the same Click to see full answer Beside this, what is the rule for a reflection across the X axis? · When you reflect over xaxis the coordinates are (x,y) and when you reflect over the yaxis the coordinates are (x,y If you want to reflect over y=x then the coordinates are (y,x) If you want to reflect over y=x the coordinates are (y,x) Comment on Caylen Jang's post "You can use aReflection about the line y = x Once students understand the rules which they have to apply for reflection transformation, they can easily make reflection transformation of a figure Let us consider the following example to have better understanding of reflection
Q Reflect the point (2, 4) over the yaxis Q Point C (5, 4) is reflected over the xaxis What are the coordinates of C'?Similarly, let's reflect this over a vertical line This line represents because anywhere on this line is , it doesn't matter what the value is We'll treat this the same way as we treat everything so far in reflection Point is spots away from the axis so we'll go spots below it And we end up withQ ∆QRS contains the points Q (4, 2) R (5, 1) S (3,7) If the triangle is reflected across the yaxis, what will S' be?

1617 · A reflection is an example of a transformation that takes a shape (called the preimage) and flips it across a line (called the line of reflection) to create a new shape (called the image) The most common lines of reflection are the xaxis, the yaxis, or the lines y=x or y=−xMICHAEL ANDERSON So hopefully, we've got enough coordinate points to maybe see a pattern, maybe find a rule about what happens when we reflect something in the line y equals x If we look at it, well, negative 6, negative 2 becomes negative 2 and– oohPractice Exams Final Exam
