Answer:
C)  1 ≤ x ≤ 9 or x is between 1 and 9, inclusive
Step-by-step explanation:
The straight line passes through the points (1, 2) and (9, 14)
The domain represents the x-values of the graph.
Here the x-values from 1 to 9 inclusive.
Therefore, Â the domain = [1, 9]
Answer:  1 ≤ x ≤ 9 or x is between 1 and 9, inclusive.
