We are asked to find the value of the ceiling function: 
As we know that the ceiling function always occupy the higher value in integers.
i.e. the ceiling function act as follows:
it takes value 0 when -1< x≤0
1 when 0 < x ≤ 1
2 when 1 < x ≤2
and so on.
As we know that:
-4.6 lie between -5 and -4.
Hence, we have:

Answer:
It is a negative correlation
Step-by-step explanation:
As the x value increases the y value decreases. This causes it to be a negative.
Since +(-2.4) is simply +1(-2.4), we get 19-1.67-2.4=14.93
