<u>Answer</u>
2nd diagram
<u>Explanation.</u>
When contraction a parallel line from a point say N, outside the line, the first thing is to draw a line from point N to the that line. 
The point where this line from N intersect with line, name it say P. From this point you can use the properties of angles in a parallel lines to construct the parallel line. 
The line NP can act like a transverse of the two parallel lines. The diagram 2 shows first step.

Answer:
The change in x = Δx =  -1
Step-by-step explanation:
Given the ordered pairs
Here, 
Change in x can be calculated by subtracting the value of x₁ = 6 from x₂ = 5.
Change in x = Δx = x₂ - x₁ = 5 - 6 = -1
Thus, the change in x = Δx =  -1
