The solution of parallel lines will have the same slope but different y-intercepts. The solution of same/coinciding lines will have the same slope and y-intercept.
2 + 17x - 5x + 9
First, subtract 17x - 5x to get 12x.
Second, leave the 12x be and add 2 + 9 to get 11.

Answer:
12x + 11
The answer to the question
Answer:
2,600
Explanation:
Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.
