How do you graph the inequality #2x+y< -3#?
See a solution process below:
First calculate two points on the line for this as an equation instead of an inequality to find the border of the inequality:
We can now plot these two points and draw a line through them to find the border of the inequality:
Now that we have the border we can chart the inequality. Because the inequality operator contains a "or equal to" clause it will stay as a solid line. And because it has a "less than" clause we will shade to the left of the line:
