Step-by-step Solution
To graph the inequality \( -5x - y < 4 \), we can follow these steps:
1. **Rewrite the inequality**: First, we can rearrange the inequality into slope-intercept form (y = mx + b).
\[
-y < 5x + 4
\]
\[
y > -5x - 4
\]
Note that we flipped the inequality sign when we multiplied by -1.
2. **Graph the boundary line**: The boundary line is given by the equation \( y = -5x - 4 \). To graph this line, we can find two points:
- When \( x = 0 \):
\[
y = -5(0) - 4 = -4 \quad \text{(Point: (0, -4))}
\]
- When \( x = 1 \):
\[
y = -5(1) - 4 = -9 \quad \text{(Point: (1, -9))}
\]
Plot these points on the graph and draw a dashed line through them, since the inequality is strict (<), indicating that points on the line are not included in the solution.
3. **Shade the appropriate region**: Since the inequality is \( y > -5x - 4 \), you will shade the region above the line. This represents all the points where the y-value is greater than the corresponding y-value on the line.
4. **Final graph**: The final graph will show a dashed line representing \( y = -5x - 4 \) with the area above the line shaded.
If you have graphing software or graph paper, you can plot this accordingly.
Quick Answer
Graph the inequality \( y > -5x - 4 \) by plotting the line \( y = -5x - 4 \) with a dashed line and shading the region above it.
