Given y=6-[sqrt(4-3x)], focus on the sqrt function: sqrt(4-3x). Since the input of this function cannot be negative, any x-value used must pass the test 4-3x>0. This is equivalent to 4>3x, or 3x<4, or x < 4/3. This eliminates choice E.
Second, if the y value is an integer, then sqrt(4-3x) must be an integer.
Checking answers A through D:
A: sqrt(4-3) = sqrt(1) = 1 (OK) Then y=6-[sqrt(1)] = 5 (NO)
B: sqrt(4-0) = 2 (OK) Then y=6-2 = 4 (NO)
C: sqrt(4-0) = 2 (OK) Then y=6-2 = 4 (NO)
D: sqrt(4-15) Not OK; eliminate

Answer:
Step-by-step explanation:
Center of dilation: O(9,0).
Line AB with A(-3,-4) and B(5,-4) is dilated with the scale factor k and center of dilation at O to form line A'B' with A'(6,-1) and B'(8,-1).
