# How do you graph the inequality #20 > 2x+2y#?

##### 1 Answer

See a solution process below:

#### Explanation:

First, solve for two points as an equation instead of an inequality to find the boundary line for the inequality.

**For:**

**For:**

We can now graph the two points on the coordinate plane and draw a line through the points to mark the boundary of the inequality.

graph{(x^2+(y-10)^2-0.25)((x-10)^2+y^2-0.25)(2x+2y-20)=0 [-30, 30, -15, 15]}

Now, we can shade the left side of the line. We need to also make the boundary line a dashed line because the inequality operator does not contain an "or equal to" clause.

graph{(2x+2y-20) < 0 [-30, 30, -15, 15]}
