Question
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.
Step 1
This is done by graphing the line $x+y=3$. The x-intercept of this line is at $x=3, y=0$ and the y-intercept is at $x=0, y=3$. Show more…
