You can put this solution on YOUR website! y<1
First, establish a boundary line by using an equal sign:
y=1 (see the graph:
.
In this case, the boundary line will be a dashed line because the inequality is "less than" "1". If the inequality had been just "less than or equal to", the boundary line would have been a solid line instead.
.
Now, shade every thing below or less than the line (which is everything < 1) since "y" is every point less than the line (see the graph below):
