Answer:

Step-by-step explanation:
You can notice that between each of the arithmetic sequence there is a addition of 2. So we know that to add a 2 to get the next value. We can write it as n(x) where n is a function where x is the number:
- n is the function and x repersent the number which is given
- We can write this function as:

- So if we input x = -5 we will get -7. If we input -11 we get -13.
The only way that 2 lines can intersect more than 1 time is if they are the same line, then they intersect infinitely
if they are differnet lines, then they can only intersect 1 time at max
