Triangle RST has vertices:
R(-4,2)
S(3,5)
T(-4,-4)
Then, the triangle is moving to the left you subtract the number of units from the x coordinates of each vertex of the triangle.
And the triangle is moving down, you subtract the number of units moved down from the y coordinates of each vertex. So:
For R'

For S'

For T'
