(x,y) is a coordinate.

Answer 6

Answer 7

To make it reflect across the y-axis you have to multiply the x coordinate by -1.
To make it shift 2 units down you have to subtract 2 from the y coordinate.

Answer 8

Do that to every point in the triangle.

Answer 9

At the end just connect the dots to get the shifted triangle.
