Answer:
4 is the median to your problem
This is easier than you think!
When a graph shows direct variation, it always <em>passes through the origin</em>
The origin is (0, 0)
The very <u>center! </u>
Your answer is the first graph!
Factor the expression:
-1/6*6(x-2y)
Divide by 6
-1(x-2y)
Then times by -1
-x+2y
Is your answer
Hope this helps
They are all even numbers
