To work out the equation of a line from a graph, find the gradient and the \(y\)-intercept. The gradient is the same all along the line, so it doesn’t really matter where you start or finish ...

In order to work with gradients and straight lines successfully ... c\) is the \(y\)-intercept (1). The equation is \(y = 3x + 1\) Practise reading and plotting quadratic graphs with this quiz.

Any equation that can be rearranged into the form \(y = mx + c\), will have a straight line graph. \(m\) is the gradient, or steepness of the graph, and \(c\) is the \(y\)-intercept, or where the ...

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 - x\) (which can be re-written as ...
