Coordinate Geometry
Coordinates locate points. Gradient measures rate of change; horizontal and vertical changes must be taken in the same direction.
Key ideas
- gradient
- midpoint introduction
- distance on grid
- line rules
- parallel lines
Formula / rule: gradient=(y₂−y₁)/(x₂−x₁).
Worked example: from (1,2) to (4,8), gradient = 6/3 = 2.
Common trap: Use matching point order in numerator and denominator.
Key words
gradient — Δy/Δx
midpoint — point halfway between endpoints
intercept — axis crossing
parallel — same direction, no intersection
coordinate — ordered pair
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 30 attempts on the same browser.
