algebraWhich inequality represents the shaded region on a coordinate plane above the line ?
A
B
C
D
Correct Answer: A
Choice A is the correct answer. Interpret the shading and line type.
- "Above": Shading above the line corresponds to or .
- "Strictly above": Usually implies a dashed line (though not specified, "above" usually means ). If the line were included, it would say "on or above". Let's assume strict inequality for "above".
- Result:
?�� Strategic Tip: shades up/above. shades down/below.
Choice B is incorrect because it shades below. Choice C is incorrect because it includes the line (), which is "at or above". Without "dashed/solid" info, A is the safest bet for "above". Choice D is incorrect because it shades below.
