The equation given is $y = 2x + 10$. This equation is in slope-intercept form, $y = mx + b$, where:

• $m$ represents the slope of the line.
• $b$ represents the $y$-intercept.

The $y$-intercept is the value of $y$ when $x = 0$. From the equation $y = 2x + 10$, we can see that $b = 10$.

Thus, the $y$-intercept of the line is $10$, which corresponds to the point $(0, 10)$.

Would you like more details or have any questions? Here are five related questions to expand your understanding:

1. How do you calculate the slope of a line from its equation?
2. What does the slope represent in the context of this equation?
3. Can the $y$-intercept change if the slope or another part of the equation changes?
4. How do you find the $x$-intercept of a line given its equation?
5. Can a line have more than one $y$-intercept? Why or why not?

Tip: Always remember that the $y$-intercept is the constant term in the slope-intercept form $y = mx + b$.
