Chloe wants to show x > 2 on a number line.
She draws a solid circle at 2 with an arrow pointing to the right.
Explain the mistake Chloe has made.
Write down the greatest integer that satisfies 4x − 3 < 18
4 marks
Show answer
a) The circle at 2 should be open, not solid, because x > 2 does not include 2b) 5
