Answer:
1: No, x is raised to a power
2: Yes, can be solved in the form of y = mx + b
3: If this is supposed to be x + y = 45, then yes because it can be solved in the form of y = mx + b
4: Yes, it is in the form of y = mx + b
5: Yes, it is in the form of y = mx +b, it has a slope of zero and will be a horizontal line, which will pass the vertical line test
6: No, x is raised to a power.
7: No, x is raised to a power.
8: No, x is raised to a power
9: Is that supposed to be pi? If so, yes, it is in the form of y = mx + b
