You used the fact that you can multiply both sides of an equality by the same, non-zero constant.
So, if you start with the trivial equality
you can multiply both sides by 3:
But if 
, 
becomes 
, which is 
. So, we have
which leads to
if you recall that

Answer:
C
Step-by-step explanation:
The correlation is becoming stronger, with a negative direction.
The closer a number is to the zero in the number line when its negative the more value it has.
Now if the number is negative and its away from zero in the number line the less value it has.
Answer:
Option D <em>The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values </em>is correct option.
Step-by-step explanation:
At x-axis we have number of hours worked and y-axis represents earnings in dollars.
We can make the table:
Number of hours worked (x) earnings in dollars (y)
1 12
2 24
3 36
4 48
5 60
Now, we need to find the pattern.
If we add 1+ 11 we get 12, but if we add 2+ 11 we get 13 and not 24 so, the pattern is not additive.
Now, if we multiply 1 by 12 (1 x 12) we get 12,
then 2 x 12 = 24
3 x 12 = 36
4 x 12 = 48
and 5 x 12 = 60
The same number if multiplied with x-axis we get y-axis.
So, the pattern is multiplicative. and we are multiplying 12 with the number of hours worked, so the correct option is option D.
Option D <em>The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values </em>is correct option.
