Math Problem Statement
This is the graph of a linear inequality. Write the inequality in slope-intercept form.
Solution
The graph shows a linear inequality with shading below a line, which indicates the region where the inequality holds. Let's analyze the line’s slope and y-intercept to write the inequality in slope-intercept form.
Step-by-Step Solution:
- Identify two points on the line: Looking at the line, two clear points are (0, -1) and (1, 0).
- Calculate the slope (m): So, the slope .
- Determine the y-intercept (b): The line crosses the y-axis at -1, so .
The equation of the line is:
- Determine the inequality symbol: Since the shaded region is below the line, we use (for “less than or equal to”) to include the boundary line.
Final Answer:
The inequality is:
