Which is the correct number-line form of \(5x+2\le 3x-6\)?

Answer and explanation

Correct answer: closed point at \(-4\), shaded to the left

From \(5x+2\le 3x-6\), subtract \(3x\) from both sides to get \(2x+2\le -6\). Subtracting 2 gives \(2x\le -8\), hence \(x\le -4\). Since \(\le\) includes \(-4\), the number line has a closed point at \(-4\) and is shaded to the left for smaller values. Option B incorrectly excludes \(-4\). Exam tip: use a closed point for \(\le\) or \(\ge\), and an open point for \(<\) or \(>\).
