Reflection Step 1: If reflecting across the {eq}x The $y = x$ reflection is a type of reflection on the Cartesian plane where the pre-image is reflected with respect to the line of reflection with an equation of $y = x$. So in that case, we're gonna have Y is equal to not just negative X squared, but negative 1/4 X squared. Doing homework can help you learn and understand the material covered in class. Auto Flip Flip Share this Graph $$(2,0) \mapsto (-4,0)$$. The line becomes quite steep when you have a whole number; a fraction causes the line to be less steep. Similarly, if you seek to install the Tea Coffee Machines, you will not only get quality tested equipment, at a rate which you can afford, but you will also get a chosen assortment of coffee powders and tea bags. Why isn't the work for THAT shown? (y1 + y2) / 2 = 3. y1 + y2 = 6. A reflection that results in an overlapping shape. y=x But when X is equal to negative one, instead of Y being equal to one, it'd now be equal to negative one. To reflect $\Delta ABC$ over the line $y = x$, switch the $x$ and $y$ coordinates of all three vertices. Same thing here.
