Input up to 10 shape (x,y) coordinates below: X: Y: Click any button below to multiply the. What is important to note is that the line of reflection is the perpendicular bisector between the preimage and the image. Point Z is located at $$ (2,3) $$ , what are the coordinates of its image $$ Z'$$ after a reflection over the x-axis, Point Z is located at $$ (-2, 5) $$ , what are the coordinates of its image $$ Z'$$ after a reflection over the line $$y=x$$, Point Z is located at $$ (-11,7) $$ , what are the coordinates of its image $$ Z'$$ after a reflection over the y-axis, Point Z is located at $$ (-3, -4 ) $$ , what are the coordinates of its image $$ Z'$$ after a reflection over the x-axis, $ A transformation takes a basic function and changes it slightly with predetermined methods. Note that there are two formulas for R1: one where R1 is greater than the characteristic impedance of the line . If the center of rotation is the origin, input : 0 0, - Line : m p : if the line equation is y = mx+p, then input m (slope) and p (intercept) separated by a space. Construct a line of reflection given the object and the image. Take any function f(x) and change x to x + c, the graph of f(x + c) will be the graph of f(x) shifted horizontally c units. Reflection is the mirror image of the original object. For the direction, a horizontal shear (or transvection) is a shear that is parallel to x-axis. The notation for this is r y a x i s. The transformation for image B to form image C is a rotation about the origin of 90 C W. The notation for this transformation is R 270 .
