Remark
When talking about straight lines, D is never true. Never.
C is possible, but in this case not true. Read on.
B. Might be true but in this case it is not. The lines (to be parallel) have to have the same number in front of the x. These two lines do when you divide through by 5. But the y intercept has to be different. That is not so in this case. So B is incorrect.

Answer:
2.1
Step-by-step explanation:
Use the equation
Sum of elements = average x number of elements
sum = (6)(4)
sum = 24
Add up the numbers we know: 3.4 + 10.7 + 7.8 = 21.9
24 - 21.9 = 2.1
This means the fourth number is 2.1
7+d=19 is the answer
subtract 7 from each side d=19-7
d=12
