Here is the graph of the function $f(x) = 2x$. If you'd like to explore further details or have any questions about this graph, feel free to ask!

Here are five related questions you could explore:

1. What happens to the graph if the slope changes to 3, making $f(x) = 3x$?
2. How would the graph change if a constant is added, such as $f(x) = 2x + 1$?
3. What is the slope of a horizontal line, such as $f(x) = 2$?
4. How does the function $f(x) = -2x$ compare to $f(x) = 2x$?
5. What is the effect of multiplying the function by a scalar, for example $f(x) = 4(2x)$?

Tip: The slope of a linear function determines how steep the graph is—higher slopes result in steeper lines!
