Answer
A. The slope is 2.
B. The \( y \)-intercept is 7.
Solution
It seems that I am unable to generate a graph at this moment. However, I can guide you on how to graph the equation \( y = 2x + 7 \) manually.
### Steps to Graph the Equation:
1. **Plot the \( y \)-intercept**: Start by marking the point \( (0, 7) \) on the graph. This is where the line crosses the \( y \)-axis.
2. **Use the slope**: The slope of \( 2 \) means that for every \( 1 \) unit you move to the right (positive \( x \)), you move \( 2 \) units up (positive \( y \)). From the point \( (0, 7) \):
- Move \( 1 \) unit to the right to \( x = 1 \).
- Move \( 2 \) units up to \( y = 9 \).
- Plot the point \( (1, 9) \).
3. **Draw the line**: Connect the points \( (0, 7) \) and \( (1, 9) \) with a straight line, extending it in both directions.
### Final Summary
- The slope is \( 2 \).
- The \( y \)-intercept is \( 7 \).
You can use graph paper or a graphing tool to visualize the line based on these points. If you have any further questions or need additional assistance, feel free to ask!

Beyond the Answer
The slope of the line \( y = 2x + 7 \) is 2, which means for every unit increase in \( x \), \( y \) increases by 2 units. The \( y \)-intercept is 7, indicating that the line crosses the \( y \)-axis at the point (0, 7). To graph the equation, start at the \( y \)-intercept (0, 7) on the graph. From there, use the slope of 2 to rise 2 units up and move 1 unit to the right to mark your next point (1, 9). Connect these points with a straight line, and you’ll see the linear relationship clearly represented!
