1. which is a rule that describes the translation of point from (-5, 4) to (-1, 2)
A (x,y) --> (x - 4, y - 2)
B (x,y) --> (x + 4, y - 2) (my answer)
C (x,y) --> (x + 4, y + 2)
D (x,y) --> (x - 4, y + 2)
2. the ordered pairs (2, -17) and (5, -35) are solutions to which of the following equations?
A y = -6x +5
B y = 6x -5 (my answer)
C y = 6x + 5
D y = -6x -5
3. the point D (x,y) is reflected over the y-axis. Use arrow notation to describe the original point and its reflection.
A (x,y) --> (-x,-y) (my answer)
B (x,y) --> (x,-y)
C (x,y) --> (-x,y)
D (x,y) --> (2x,y)

there is no #4 btw
#1 ok
#2 Nope. Check your signs carefully.
#3 Nope. Plot a point and fold the paper along the x-axis. Where does the point go?
