Year 9 · Maths
Use coordinates in all four quadrants in Year 9 Maths
Start here
Focus on finding the midpoint of a line segment. Start with “Calculate the Equation of a Straight Line Given Two Coordinates”, then explain the idea in your own words.
Year 9 learners practise finding the midpoint of a line segment.
The activities include Calculate the Equation of a Straight Line Given Two Coordinates, Find the Coordinates of the Midpoint of a Line Segment, Identify if a Coordinate Point Lies on a Straight Line of Equation y = mx + c. The checked support below includes video, worksheet, teaching, lesson. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
Activities covered
- Calculate the Equation of a Straight Line Given Two Coordinates
