Triangle ABC is shown on the graph below.

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.

1. sorry I could not add the link but the coordinates are A(1,3) B(4,5) and C(3,1).

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

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

Now just plug in your numbers.
