1. Problem Description
The problem asks to graph the inequality .
2. Solution Steps
First, we rewrite the inequality in slope-intercept form, which is , where is the slope and is the y-intercept.
Subtract from both sides:
The corresponding equation is . This is a line with a slope of and a y-intercept of .
Since the inequality is strictly less than, we draw a dashed line to indicate that the points on the line are not included in the solution.
To determine which side of the line to shade, we can test a point that is not on the line. A convenient point is .
Substitute and into the inequality :
Since this is true, we shade the region containing the point . This is the region below the line.
3. Final Answer
The solution is the region below the dashed line . The line has a y-intercept of 1 and a slope of -
