Find the gradient and y-intercept for the straight line with equation \(2x + y - 13 = 0\). Rearrange the equation into the form \(y = mx + c\) using the algebraic rules for solving equations.

This is known as the gradient. \(c\) is the number where the line crosses the \(y\)-axis. This is the \(y\)-intercept. To draw a graph of \(y = mx + c\) for given values of \(x\): Use the pairs of ...

you can write the equation of the line as: You can then simplify this equation to other forms, such as the slope intercept form, where the equation of the line is expressed as y = mx + b ...
