If the equation of a linear line is given in general form, then it can be graphed by doing the following:
- Calculate the y-intercept and gradient of the line
- Locate the y-intercept on the Cartesian plane given by the constant in the equation.
- Determine the rise and run of the line by using the coefficient of x.
- Use the rise and run from the y-intercept to locate a second point on the Cartesian plane.
- Use a ruler to rule the linear line.
