Answer 1

To graph the equation \( y = 7x + 5 \), we can follow these steps:

1. **Find the y-intercept**: The y-intercept is the point where the line crosses the y-axis. This occurs when \( x = 0 \).
\[
y = 7(0) + 5 = 5
\]
So the y-intercept is the point \( (0, 5) \).

2. **Plot the first point**: The first point based on the y-intercept is \( (0, 5) \).

3. **Use the slope to find the second point**: The slope of the line is \( 7 \), which means for every 1 unit we move to the right (positive x direction), we move up \( 7 \) units (positive y direction).

Starting from the y-intercept \( (0, 5) \):
- Move right 1 unit to \( x = 1 \)
- Move up \( 7 \) units from \( y = 5 \) to \( y = 5 + 7 = 12 \)

This gives us the second point \( (1, 12) \).

4. **Summary of points**:
- The first point (y-intercept): \( (0, 5) \)
- The second point: \( (1, 12) \)

You can now plot these points on a graph and draw a line through them to represent the equation \( y = 7x + 5 \).
