Triangle ABC is shown on the graph below.

link to picture

a. Triangle ABC is reflected over the y-axis. What are the coordinates of the reflected triangle?
b. Describe in words what happens to the x-coordinates and the y-coordinates of the original triangle's vertices as a result of this reflection.
I need help please!!

  2. reflection over the y-axis just changes the signs of the x values:

    (x,y) -> (-x,y)

    Now just plug in your numbers.
