Graphs & Coordinate Geometry
Coordinate Geometry
Finding gradients, midpoints, and lengths of line segments. Equations of straight lines in y = mx + c form.
Linear Graphs
Plotting and interpreting straight-line graphs and solving simultaneous equations graphically.
Quadratic & Further Graphs
Recognizing and sketching quadratic, cubic, and reciprocal functions. Finding roots and turning points.
Tangents in a Graph
Estimating the gradient of a curve by drawing tangents and calculating the rate of change.
Graphing Inequalities
Shading regions on a coordinate grid to represent linear inequalities and identifying feasible regions.
Distance-Time Graphs
Interpreting slopes as speed, calculating total distance, and analyzing movement over time.
Speed-Time Graphs
Interpreting gradient as acceleration and area under the curve as total distance traveled.
