Question

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

Answer 1

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.
