WebHow do we interpret inequalities on a graph? First, see Straight Line Graphs (y = mx + c) To interpret inequalities/ to find a region defined by inequalities; Write down the EQUATION of each line on the graph REMEMBER that lines are drawn with: A solid line for ≤ or ≥ (to indicate line included in region) WebYou need to be able to use the basic conversions. 1 cm 2 = 10 2 mm 2 = 100 mm 2. 1 m 2 = 100 2 cm 2 = 10 000 cm 2. 1 km 2 = 1000 2 m 2 = 1 000 000 m 2. There are also less common conversions. 1 hectare (ha) = 10 000 m 2. If you are given an imperial conversion (such as miles to kilometres) for lengths: Write the conversion as a ratio.
