Answer: D
Step-by-step explanation:
The orange color is represented by the bottom line, which is y > x - 2
The purple color is represented by the top line, which is y < x + 1
How do we know the equations of those lines?
- The equations can be written in the form y = mx + b where;
- m = slope
- b = y-intercept
The orange line:
- crosses the y-axis at -2 --> b = -2
- has a rise over run of 1 -> m = 1
- --> y = x - 2
- the line is dashed and is shaded above so y > x - 2
The purple line:
- crosses the y-axis at +1 --> b = 1
- has a rise over run of 1 -> m = 1
- --> y = x + 1
- the line is dashed and is shaded below so y < x + 1
