How do you graph the inequality # x + y ≥ 5# and #x – 2y> 8#?
1 Answer
Plot the line and use a point determine which side is to be shaded
Explanation:
To graph any inequality, we must first draw the line it forms.
An inequality is the the shaded portion and represents a set of values.
Take the first inequality;
First draw the line
graph{5-x [-10, 10, -5, 5]}
It looks like this. Now the inequality will appear as this line with one side shaded. To determine which side is to be shaded, take a simple point
When the inequality contains
Now that you know how to do it, give the second one a shot :)
