The graph you uploaded shows a straight line on a coordinate plane. To determine the domain and range of this linear function, we analyze the characteristics of the line:

1. Domain: The domain refers to all possible values of $x$. Since the line extends infinitely in both horizontal directions (left and right), the domain includes all real numbers.

   Domain: $(-\infty, \infty)$

2. Range: The range refers to all possible values of $y$. Similarly, because the line extends infinitely in both vertical directions (up and down), the range also includes all real numbers.

   Range: $(-\infty, \infty)$

Would you like further details on the graph's equation or any other aspect?

Here are 5 related questions to expand this topic:

1. How do you find the equation of a line given its graph?
2. How can you determine the slope of a line by looking at its graph?
3. What is the relationship between the slope of a line and its steepness?
4. How does changing the slope or intercept affect the appearance of a line on a graph?
5. How do domain and range differ for non-linear functions?

Tip: When analyzing straight lines, always check if they extend infinitely in both directions to determine their domain and range, as most lines will have a domain and range of all real numbers unless restricted.
