Think About It After graphing the boundary of the inequality $x+y<3$ , explain how you decide on which side of the boundary the solution set of the inequality lies.
Added by Paul W.
Step 1
First, we graph the boundary line by treating the inequality as an equation: $x+y=3$. This is a straight line with a slope of $-1$ and a $y$-intercept of $3$. Show more…
