If you put it in slope intercept form, you will have:

.
If you converted the format, you could also have:

.
The rest of the choices are a different graph.
The angle would be 70 degrees because 180-110=70
They are the same because they have the same slope but are different because they have different y intercepts.
Answer:
8.7 in
Step-by-step explanation:
a = 7.3
b = 4.8
c^2 = 7.3^2 + 4.8^2 = 76.33
c = sqrt(76.33) which is around 8.7
