Write down the inequality in the underlined part in 7 ___ 3 , A _____ B
2. Move points A and B such that to get on the number line A = 2 and B = -4.
Write down the inequality in the underlined part in 2 ___ -4 , A _____ B
3. Move points A and B such that to get on the number line A = -5 and B = -1.
Write down the inequality in the underlined part in -5 ___ -1 , A _____ B
4. Move points A and B such that to get on the number line A = -2 and B = 4.
Write down the inequality in the underlined part in -2 ___ 4 , A _____ B
What happens when you multiply both A and B by -1 equally for each of the tasks from 1 to 4 ? ie
5. From 1, after multiplying by -1, A = -7 and B = -3.
Move A and B as before and observe.
