Graph is given. You are expected to be able to find the equation(linear or any other form), locate the gradient(m) and the y-intercept(c). Usually appears in Paper 1.
Required to draw/plot the linear graph on graph paper with no fixed scale. Table of values will be given(x & y).
Try to use 2/3 of the graph paper, do not just extend the axis without extending the graph. Intermediate working should be more than 3 significant figures with the final answer rounded off to 3 significant figures.
Remember to put the title(e.g. log y against log x)
