Triangle xyz has vertices x(0,3), y(2,0) and z(4,2). if yo reflect triangle xyz across the line x=4, what will be the coordinates of the vertices of the image triangle x1,y1,z1

As X' is the reflected point of X(0,3) , so the x co ordinate of X' = 0+8 =8 and here y co ordinate remains same.

So, X'= (8,3)

Like that way, Y' is the reflected point of Y(2,0) and Z' is the reflected point of Z(4,2)

As the point Z is lying on the line x=4 and the reflection is also across that line, so both Z and Z' represent same point.

Y'= (2+4, 0) = (6, 0)

Z' = (4, 2)

y=x+9
