A Formula to Reflect a Point in y = −x Using Cartesian Coordinates In general, we write Cartesian coordinates as x is the xcoordinate y is the ycoordinate x and y can taken any number The reflected point has Cartesian coordinates The image below shows a general Cartesian coordinate being reflected in the line y = −xReflection across the yaxis y = f (− x) y = f(x) y = f (− x) Besides translations, another kind of transformation of function is called reflection If a reflection is about the yaxis, then, the points on the right side of the yaxis gets to the right side of the yaxis, and vice versa 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)
Reflection across the xaxis 9 Reflection across the yaxis, followed by Translation (x 2, y) The vertices of ∆DEF are D(2,4), E(7,6), and F(5,3) Graph the preimage of ∆DEF & each transformation 10 Translation (x 3, y – 5), followed by Reflection across the yaxis 11 Reflection across the y – axis, followed byIn the above function, if we want to do reflection through the yaxis, x has to be replaced by x and we get the new function y = f (x) The graph of y = f (x) can be obtained by reflecting the graph of y = f (x) through the yaxis It can be done by using the rule given belowAnswer (1 of 3) Remember that when a point P(x, y) of the coordinate plane is reflected in the y axis , it becomes the point Q(x, y) and when reflected in x axis, it becomes P'(x, y) Therefore the quadratic p(x) = ax^2 bx c (a not zero) when reflected in y axis it becomes ;
In these printable worksheets for grade 6 and grade 7 reflect the given point and graph the image across the axes and across x=a, y=b, where a and b are parameters This practice set tasks 6th grade and 7th grade students to identify the reflection of the given point from the given options Reflect the point across the line of reflectionFor example, if we are going to make reflection transformation of the point (2,3) about xaxis, after transformation, the point would be (2,3) Here the rule we have applied is (x, y) > (x, y) So we get (2,3) > (2,3) Let us consider the following example to have better understanding of reflection Question1) a line reflection over y =x 2) a rotation of 180° centered at (1,0) 3) a line reflection over the xaxis followed by a translation of 6 units right 4) a line reflection over the xaxis followed by a line reflection over y =1 4 In the diagram below, A′B′C′ is a transformation of ABC, and A″B″C″ is a transformation of A′B′C′

Reflection across the xaxis y = − f ( x) y = f (x) y = − f ( x) The concept behind the reflections about the xaxis is basically the same as the reflections about the yaxis The only difference is that, rather than the yaxis, the points are reflected from above the xaxis to below the xaxis, and vice versa Basic ConceptsA reflection is a flip over a line You can try reflecting some shapes about different mirror lines here How Do I Do It Myself?Xyplane, the x and ycoordinates stay the same, but the zcoordinate becomes zero The formula for the transformation is then T x y z = x y 0 ⇀u x T ⇀u y z Let's now look at the above example in a different way Note that the xyplane is a 2dimensional subspace of R3 that corresponds (exactly!) with R2 We can therefore look at the
