To graph the inequality \( y < x + 5 \), follow these steps:
-
Graph the Boundary Line:
- The boundary line is given by the equation \( y = x + 5 \). This is a straight line with a slope of 1 and a y-intercept of 5.
- To graph this line, plot the y-intercept at (0, 5).
- From that point, use the slope to find another point. Since the slope is 1, you can go up 1 unit and right 1 unit to find the point (1, 6), or down 1 unit and left 1 unit to find (−1, 4).
- Connect these points with a dashed line because the inequality is strict (<), indicating that points on the line are not included in the solution set.
-
Shade the Appropriate Region:
- Since the inequality is \( y < x + 5 \), you will shade the area below the line. This means for any point in this shaded region, the y-value is less than the corresponding y-value of the line.
Here’s a summary of the graphing steps:
- Draw a dashed line for \( y = x + 5 \).
- Shade the region below this line.
Graph Representation
If you were to visualize this graph:
- The x-axis runs horizontally, and the y-axis runs vertically.
- Mark the line \( y = x + 5 \) with a dashed line.
- Shade everything below this line.
This shaded region represents all the points \((x, y)\) that satisfy the inequality \( y < x + 5 \).
