у 4 2+ +x 4 -4 -2 2 2+ Which of the following inequalities is graphed on the coordinate plane? OA. y = 2a + 2 OB. y > 21 + 2 Oc. y > 2x + 2 OD. y < 2x + 2 2 ​

Answer 1

C. y ≥ 2x +2

Explanation:

To determine which inequality is graphed, you need to look at two things:

• is the shading above or below the line
• is the line solid or dashed

Here, the shading is above a solid line. That means the relation is ...

y ≥ ( )

"greater than" means the y-values greater than those on the line are the ones in the solution set. (Shading is above the line.)

"or equal to" means the boundary line is included in the solution set, so it is graphed as a solid line.

Only one answer choice has the correct inequality symbol:

y ≥ 2x +2

Additional comment

The boundary line equation itself is the same for all answer choices, so this is entirely about the inequality symbol.
