# How do you graph the inequality a + b<12?

See below:

#### Explanation:

It will look like this:

graph{y<12-x [-20, 20, -15, 15]}

The shaded area is the solution.

The line has a slope of $- 1$, passes through the y axis at $y = 12$, and has a dotted line to indicate that the line itself is not a solution.
