Interpreting straight-line graphs
Read the evidence and keep a control room's systems running.

COURSE LIBRARY
Every year has its own course space. Year 10 is open now; new courses and chapters will appear inside the same structure as they are released.
ACTIVE COURSE
Straight lines, gradient, intercepts, modelling, variation and non-linear graphs.
6J–6N now have a two-page classroom lesson, one-page matching homework and a separate teacher answer key. Resources for 6A–6I are unchanged.
Read the evidence and keep a control room's systems running.
Control RoomReplay journeys and schedule movements, stops and return trips.
Dispatch LabCalculate and deploy your own navigation beacons.
Beacon WorkshopUse signed slopes to engineer ramps and routes.
Gradient WorksMeasure changing systems and choose safe operating rates.
Rate StationNavigate a metro network using linear equations.
Metro Linear ChallengePlan a city network using related gradients.
City Grid ChallengeRestore systems by finding and plotting intercepts.
Axis CalibrationDecode data and build models for live missions.
Model ShiftCalibrate materials, scale a batch and plan a delivery.
Scale WorksAllocate pumps and crews while keeping total work constant.
CounterbalancePlace sensors, fit a roof and check a vehicle's clearance.
Curve WorksFit a photo, size a tile pattern and power a growing light display.
Make It GrowPlan purchases, choose a collection jar and stop water treatment safely.
Make the Right CallThe structure is already ready for Year 7, 8, 9, 11 and 12. Adding the next course will expand the library without changing how students find their work.
