About this printable

This printable is a compact reference mat that explains the linear equation y = mx + c, defines m (gradient) and c (y-intercept), shows the gradient-from-two-points formula and x-/y-intercept calculations, and illustrates types of lines with small graphs. It also has labelled quick-reference boxes and two blank areas for student notes or practice. Use it as a desk mat, revision prompt, or scaffold for lessons on straight-line graphs.
