Example 5.52 from Elementary Algebra, 5.6 Graphing Systems of Linear Inequalities

Graphing Systems of Linear Inequalities: example 5.52

Solve the system by graphing.

${\begin{matrix} y \geq 2 x - 1 \\ y < x + 1 \end{matrix}$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Solve the system by graphing. ${\begin{matrix} y < 3 x + 2 \\ y > − x - 1 \end{matrix}$
