Four Fours:Straight line graphs
Four lines, each described four ways: its gradient and intercept, two pairs of points and a rearranged equation. The point (1, 3) is on two of the lines and (0, 1) is on two, so one point is never enough. Two per A4.
A free key stage 3 and GCSE algebra puzzle with answers, spec codes A9 and A10. It goes with the lessons on plotting straight-line graphs, gradient of a line and the equation of a line from its graph.
