  1. Plot ΔABC on graph paper with points A(1, 1), B(–1, –1), and C(4, –1). 5-10 HW eTool (Desmos) Homework Help ✎

    1. Use the function (x → –x, yy) to transform ΔABC. Label this triangle ΔABC′. What kind of transformation does this produce? Name the coordinates of the image.

    2. Now translate ΔABC upward and right a total distance of five units, parallel to the line y = x + 5 to create ΔABC″. 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.
