Step-by-step Solution
To graph the equation \( y = -7x + 1 \) using the slope-intercept form, we can identify the slope and the \( y \)-intercept from the equation.
1. **Identify the slope and \( y \)-intercept**:
- The slope (m) is -7.
- The \( y \)-intercept (b) is 1.
2. **Plot the \( y \)-intercept**:
- Start by plotting the point where the line crosses the \( y \)-axis. This occurs at \( (0, 1) \).
3. **Use the slope to find another point**:
- The slope of -7 means that for every 1 unit you move to the right (positive direction on the \( x \)-axis), you move down 7 units (negative direction on the \( y \)-axis).
- From the point \( (0, 1) \), move 1 unit to the right to \( (1, 1) \) and then move down 7 units to \( (1, -6) \). Plot this point.
4. **Draw the line**:
- Draw a straight line through the points \( (0, 1) \) and \( (1, -6) \). Extend the line in both directions.
Now you can use a graphing tool to visualize this line. If you have access to a graphing tool, you can input the equation \( y = -7x + 1 \) directly to see the graph.
Quick Answer
Plot the \( y \)-intercept at \( (0, 1) \). Use the slope of -7 to find another point, such as \( (1, -6) \), and draw a line through these points. Use a graphing tool to visualize the line.
