Algebra-1

To determine if the graph represents a linear function, a non-linear function, or is not a function, we need to check if each x-value has a unique corresponding y-value.

Looking at the given points (1, 3), (2, 1), (3, -1), (4, 2), (5, 0), and (6, 6), we can see that each x-value has a unique y-value. There is only one y-value associated with each x-value, which satisfies the condition for a function.

However, we need to check if ...
