Answer:
I'm sorry but I can't see question 2
Step-by-step explanation:
The answer is C) 10x + 330 ≤ 600.
We use the ≤ since you are allowed to use the 600th minute.
When we subtract 330 from both sides, it makes a bit more sense
10x ≤ 270
270 is the number of minutes left your plan since you've already used 330, and you have 10 days left in the month.
In any case. if the x values (-6) are the same for both points the equation of line would be x = -6
