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.

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 ...

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 ...

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 ...

Watch this video to learn about straight line graphs of logarithmic and exponential functions. Data from an experiment may result in a graph indicating exponential growth. This implies the formula ...

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 ...

The equation of a straight line on a graph is made up of a \(y\) term, an \(x\) term and a number, and can be written in the form of \(y = mx + c\). For a line with equation \({y}={2}{x}+{ ...
