Graph the line $x=-2$. Give the domain and range.
Answer
\(\boxed{\text{Final Answer: The graph of the line } x=-2 \text{ is a vertical line that crosses the x-axis at -2. The domain of this line is } \{-2\} \text{ and the range is all real numbers, represented as } (-\infty, \infty)}\)
Step 1 ：The line $x=-2$ is a vertical line that crosses the x-axis at -2.
Step 2 ：The domain of a vertical line is just the x-coordinate where the line crosses the x-axis, which in this case is -2.
Step 3 ：The range of a vertical line is all real numbers, because the line extends infinitely in both the positive and negative y-directions.
Step 4 ：\(\boxed{\text{Final Answer: The graph of the line } x=-2 \text{ is a vertical line that crosses the x-axis at -2. The domain of this line is } \{-2\} \text{ and the range is all real numbers, represented as } (-\infty, \infty)}\)
