Here is the graph of the function $y = -4 + 2x$. The line has a slope of 2 and intersects the y-axis at -4.

Would you like more details or have any questions?

Here are some related questions for further exploration:

1. What is the slope and y-intercept of the function?
2. How would you find the x-intercept of this function?
3. How does changing the slope affect the steepness of the graph?
4. What happens to the graph if we change the y-intercept?
5. Can you calculate the values of $y$ for specific values of $x$?

Tip: When graphing a linear function, always identify the slope and y-intercept to understand how the line behaves.
