5-80.

Plot on graph paper with points , , and . 5-80 HW eTool (Desmos). Homework Help ✎

  1. Transform  by multiplying the y-coordinates of the vertices by  . Then use the function to translate the resulting triangle. Name the coordinates of the vertices of the result.

    Multiply all by . What transformation happens to the triangle?

    In the translation rule the means to move to the left , and the  means to move down . List the final coordinates for the new triangle.

  2. Rotate counterclockwise about the origin. Then reflect the result across the y-axis. Name the coordinates of the verticies of the result.

    What are the coordinates of the final figure?
