Answer: A
Step-by-step explanation:
Each value of x maps onto only one value of y.
1. D 12 2/7
2. 22 7/9 which is B hope this helps
Answer:
the answer is a
Step-by-step explanation:
Answer:
answer 2) 24
Step-by-step explanation:
after the dilation pt D is (8,-32)
after the dilation pt E is (-16,16)
if you use the distance formula for these two points you get 
which simplifies to 24
(3,4) (9,7)
to find the slope
m = (y2-y1)/(x2-x1)
= (7-4)/(9-3)
3/6
1/2
The slope is 1/2
point slope form
y-y1 = m(x-x1)
y-4 = 1/2(x-3)
distribute
y-4 = 1/2x -3/2
add 4 to each side
y = 1/2 x -3/2 + 4
y = 1/2 x -3/2 + 8/2
y = 1/2 x + 5/2
this is in slope intercept form
