Answer:
y ≥ x - 1
Step-by-step explanation:
First, determine the slope of the line. We can see that the slope is , because the slope has less than 1 y interval per every x interval. This means that the line is less steep. There are only 2 slope choices,
, -
, and 3. We can tell that the slope is positive, but it must be
because it is clearly less steep than a 3 slope line.
Now, look at the portion that is shaded. It is above the line, and this means that y is greater than the equation given. We can tell it is greater than or equal to, because the line that represents the equation is shaded as well. If it was only greater than and not equal to, the line would not be shaded.
Hope this helps ! :) Please feel free to ask me any questions!
