Answer:
E
Explanation:
We just need the last two clues. Since they said it is a line (4th clue) it could only be B, C, or E. But then, the last clue says the domain is -7. Now for almost all lines the domain is 'all real numbers'. All kinds of diagonal lines and also horizontal lines, the domain is all real numbers. Only vertical lines have a domain that is a single value. Graph E is a line that has the domain -7.
