Answer:
Step-by-step explanation:
See attachment for proper question
From the attachment, triangle DEF is an image of ABC
By comparing the position of the angles, the following sides are similar
AB to DE
AC to DF
BC to EF
By dividing the similar sides, we calculate the scale of dilation.
To calculate DF, we make use of sides AC and DF as comparison:
Substitute 2 for Scale and 2 for AC
Make DF the subject

Hello LovingAngel!
To find the slope, you can use the formulas
as well as 
. I am using the latter to calculate and ensuring my answer with the former.
[Note: (x,y) is the format for ordered pairs]
First pair: value 1:(1,5) and value 2:(2,8)
-> 
-> 
or 3.
The slope for (1,5) and (2,8) is 3(/1).
Second pair: value 1: (3,1) value 2 (3,-1)
-> 
-> 
Slope for the second pair is -2/0
Checking work with
1. Slope: 3/1, meaning rise (y) +3 and run (x) +1. (1,5) -> (1+1,5 + 3) -> (2,8) ✔
2. Slope: -2/0, meaning rise (y) -2/drop (y) 2 and run 0. (3,1) -> (3 + 0, 1 + -2) -> (3,-1) <span>✔</span>
