Answer 1

Answer:

The area below the line is shaded.

Step-by-step explanation:

Using the zero-interval test [test point (0, 0)], we plug in 0 for both y and x to determine whether we shade below the line [the portion that DOES contain the origin] or above the line [the portion that does not contain the origin]. This is where me must verify the inequality as false or true:

$\displaystyle 0 < 2[0] + 1 → 0 < 1$

This is a genuine statement, therefore we shade below the line.
