This worksheet gives an alternative view of straight-line graphs equations in the form y=mx+c and their corresponding tables of values.

Section A asks learners to complete xy-tables for given straight-line equations but highlights the fact that the intercept, c, will be below x=0, and the gradient, m, will be the common difference of the y-values generated.

Section B then asks learners to work backwards and use the facts from section A to write the equations of the lines from their xy-tables.
