1. #1, correct
#2. you have a reflection in a horizontal line, so the x value does not change.
P(4,11) was 8 units above y = 3, so the new point has to be 8 unites below y = 3
that is we want (4,-5) or D
#3.
reflection across the y-axis, leaves the y alone but switches the x to the opposite.
must be B

#4. only true for rotations that are multiples of 180°

#5. not clearly stated. Isn't A given ?

2. So if I'm not mistaken.
1. A
2. C
3. B
4. B
5.A?
So I only had 1 or2 questions correct? @Reiny

3. I ment to say:
1.A
2.D
3.B
4.B
5.C
(Sorry for 2 i hit C when I met to hit D)
(I'm guessing C because A don't seem right)

Would I be correct on 1-4 or 1-5? As in which answers is currently correct now with or with out #5 because #5 do seem tricky. But do you think it's now correct (for all of them, if you don't know for #5 it's okay to say you don't know)

7. 1. would be A, as you said
2. is is D
3. is B
4. is correct
5. is C. (1, 10) because you translate the point (-5,-4) 6 units to the right, making it (1, -4). Then you reflect that point across the line y=3. Since the coordinate is seven units below the line, you add 7 to the line's y-coordinate to get the final coordinate (1,10).
Hope that helps!
