To do this for y = 3, your x-coordinate will stay the same for both points. zero, well this is still all gonna be equal to Lets graph this now. How would reflecting across the y axis differ? this is to pick a point that we know sits on G of X, We got it right. And the best way to do $$ Let's do a couple more of these. A line reflection creates a figure that is congruent to the original figure and is called an isometry (a transformation that preserves length). {/eq}. This results in switching the places of the x and y coordinates on the coordinate system. (P) = P. Reflecting over the x-axis: (the x-axis as the line of reflection) When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite.

Graph y = f ( x) y = f (-x) y =f (x)Graph f ( x) f (-x) f (x) f ( x) f (-x) f (x) reflectionOr simply: f ( x) f (-x) f (x) Reflections $A=(0, -2)$, $B=(-2,-2)$, $C=(-2,-4)$, and $D=(0,-4)$B. A reflection over a line k (notation rk) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line. Reflection {/eq}-axis, and vice versa. What I don't know is how to solve when reflecting over something like $x = -1$. Put x = -y and y = x Original equation ==> y = 2x2 After reflection ==> x = 2y2 So, image equation of the given equation is x = 2y2. This leaves us with the transformation for doing a reflection in the y -axis. Solved example of algebraic expressions. y-axis The law of reflection formula can be written mathematically as follows. {eq}theta_i = theta_r {/eq} Here {eq}theta_i {/eq} is the angle of incidence and {eq}theta_r {/eq} is the angle of WebWhen reflecting coordinate points of the pre-image over the line, the following notation can be used to determine the coordinate points of the image: r y=x = (y,x) For example: For Reflection Across an Axis: A reflection across an axis can be imagined by picturing folding a graph that contains a point in half along one of the axes and drawing a new point where the old one falls after folding. Reflecting across the {eq}x This is, in fact, what makes the $y = x$ reflection special. Take a look at the graphs shown above the circle is reflected over the line of reflection $y = x$. says P is an element of line ?. This calculator helps you to find the point reflection A, for the given coordinates of A(x,y). Find the coordinates of the point {eq}(2,3) 77. Reflecting over any line: Each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure. Y when is X is equal to negative two instead of Y being equal to four, it would now be equal to negative four. getting before for a given X, we would now get the opposite When you reflect this point, you should end up at the same "height" ($y$-coordinate) of $-5$, but this time four units to the left of your axis of symmetry.
