    Given inequality

    • 4/5 – 1/2p ≥ 9/5

    Part A

    • – 1/2p ≥ 9/5 – 4/5           Subtract 4/5 from both sides
    • – 1/2p ≥ 5/5                    Simplify
    • – 1/2p ≥ 1            
    • p ≤ – 2 × 1                       Multiplying by negative reverses the inequality sign
    • p ≤ – 2                           Solution

    Part B

    • Mark the point – 2 on the number line as closed dot (because this point is included due to ‘less or equal’ sign) and shade the line to the left from this point.
