Math Problem Statement
Solution
The graph shows a linear inequality. From the image, we can break the problem down as follows:
-
Identify the boundary line: The line appears to pass through two points:
To find the equation of the line, we calculate the slope (m):
So, the slope .
Using the point-slope form of the line , let's use the point :
Simplifying:
-
Determine the inequality: The shaded region is below the line, which suggests that the inequality is or . Since the boundary line is solid, the inequality is .
Thus, the inequality represented by the graph is:

Tip:
Always test a point (like , if not on the line) to verify which side of the line should be shaded when graphing inequalities.
