Correct answer: the line y = x - 3
- Rewrite in slope-intercept form: is already solved for .
- Plot the y-intercept: The boundary line is , so its y-intercept is . Plot that point.
- Use the slope to plot a second point: The slope is , so from move 1 unit right and 1 unit up to reach .
- Draw the boundary line: Draw the straight line through and . In the finished solution set this boundary is drawn DASHED, because the symbol does not include equality.
