    In this lesson, we will revise the term 'gradient' and learn how to identify and calculate the gradient of a plotted line using two pairs of coordinates. We will compare lines with different gradients.

    In this lesson, we will find the equation of a straight line using y=mx+c. We will use coordinates taken from a plotted straight line to help us calculate the gradient, then use a method of substitution to find the equation of the line.
