Use the function (x → –x, y → y) to transform ΔABC. Label this triangle ΔA′B′C′. What kind of transformation does this produce? Name the coordinates of the image.
Now translate ΔABC upward and right a total distance of five units, parallel to the line y =
x + 5 to create ΔA″B″C″. Name the coordinates of the image.
Review the Math Notes box in Lesson 3.1.4.
This transformation produces a reflection over the y-axis.
Name the coordinates of each image point.
This translation is to be parallel to the line, meaning you should translate every point up 4 and to the right 3.
