first we reflect over line 1, which gives us a point above the line that mantains the x coordinate, like this:
Then line 2 will be the x-axis which is the black horizontal line, in which once again after the reflection the x coordinate will mantin the same and it will give us a point under the line. , like this:
This meand that the image will be (0,-6)
