The given equation is in slope-intercept form:

$y = 2x + 8$

In the slope-intercept form $y = mx + b$, the slope is represented by $m$ and the y-intercept is represented by $b$.

From the equation $y = 2x + 8$:

• The slope $m = 2$.
• The y-intercept $b = 8$, meaning the line crosses the y-axis at $y = 8$.

Thus, the slope of the line is 2.

Now, to answer the question:

• The correct answer is A. The slope is 2.
