Which graph correctly represents the solution to ?
Open circle at -2, shading to the left
Closed circle at -2, shading to the right
Open circle at -2, shading to the right
Closed circle at -2, shading to the left
Correct Answer: B
Choice B is the correct answer. Graphing inequalities on a number line requires understanding symbols and shading.
- Symbol interpretation: means "greater than or equal to", so include -2 itself (closed circle)
- Direction: "Greater than" means values to the right on the number line
- Result: Closed circle at -2, shading right
?�� Strategic Tip: Use closed circles for or (includes the value), open circles for or (excludes the value).
Choice A is incorrect because it uses an open circle (excluding -2) and shades left (less than), both wrong. Choice C is incorrect because while it shades right (correct direction), it uses an open circle, excluding -2. Choice D is incorrect because it has a closed circle (correct) but shades left, representing instead.
