From the question, we understand that:

This means that, the middle number is 3 (when sorted)
So, we can conclude that (b) and (c) cannot be true because their middle numbers are 6 and 5 respectively
Next, is to determine the mean of (a) and (d)
The mean of a data is calculated as:

So, we have:
(a)



(d)



Option (a) is true, because it has:


Answer:
2x - y = 6
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = 2x - 6 ( add 6 to both sides )
y + 6 = 2x ( subtract y from both sides )
6 = 2x - y, that is
2x - y = 6 ← in standard form
Answer: yes?
