Question on: JSS2 Mathematics - Linear Inequalities

Start with the inequality:

−3𝑥+6≤9

Subtract 6 from both sides:

−3𝑥≤3

Divide both sides by -3 and reverse the inequality:

𝑥≥−1

Graphical Representation:

• Draw a number line.
• Place a closed circle at 𝑥=−1(because -1 is included).
• Shade the region to the right of -1.
