How to find general form of a line. To calculate the general form linear equation for a line that includes the two points 3 1 and 3 2. Develop the slope point form for the line. The general form of the equation of a straight line is.
Suppose that we have a line in the form y mx b. Given two points x1y1 and x2y2 the slope between the points is. Xxxm y2 y1 x2 x1.
Determine the slope m. Y mx b. Converting to general form.
A or b can be zero but not both at the same time. Y2 y1 x2 x1 2 1 3 3 36 1 2. Xxxy y1 mx x1 using 12 as x1y1 and 54 as x2y2.
From the slope calculate variables a and b with the equation. For example the following math shows the procedure for converting the line y frac23x 3 into general form. The general form is not always the most useful form and you may prefer to use.
The slope point form is. Ax by c 0.
