The equation you've provided is:

$y = 2x + 40$

This is a linear equation in slope-intercept form, where:

• The slope $m = 2$
• The y-intercept $b = 40$

This means that for every unit increase in $x$, $y$ increases by 2, and when $x = 0$, $y = 40$ (the point where the line crosses the y-axis).

Would you like help with graphing this equation, solving for specific values of $x$ or $y$, or any other aspect of it? Feel free to ask!

Here are some related questions for further exploration:

1. What would the equation of the line be if the slope was -2?
2. How can we find the x-intercept of this equation?
3. How does changing the slope affect the steepness of the line?
4. What is the meaning of the y-intercept in real-life terms?
5. How do you solve for $x$ when $y = 50$?

Tip: Always remember that the slope $m$ indicates the direction and steepness of the line, and the y-intercept $b$ is where the line crosses the y-axis!
