Any equation that can be rearranged into the form \(y = mx + c\), will have a straight line graph ... in x}}\) Gradients can be: positive – going up negative – going down zero - no change ...

The graphs of \(y = 2x + 1\) and \(y = 2x - 2\) are shown below. The graph of \(y = 2x + 1\) crosses the \(y\)-axis at (0, 1). The graph of \(y = 2x - 2\) crosses the ...
