The vertices of figure HJKL are H(3,1), J(5,-2), K(1,-4) and L(1,0).  Find the coordinates if the figure is translated two units left and three units up.  

H(1,4), J(3,1), K(-1, -1), L(-1,3)

The vertices of figure STUV are S(-3,2), T(-2,4), U(3,3), and V(2,1).  Name the vertices if the image is reflected of the x-axis.

S(-3,-2), T(-2,-4), U(3,-3) and V(2,-1)
