Standard Form of a Line

The Standard Form of a line is just another way of writing the equation of a line. It gives all of the same information as the slope-intercept form or the point-slope form.

The Standard Form of a line is in the form Ax+By=C where A is a positive integer, and B, and C are integers.

Write the equation of the line y=-3x+6 in standard form.


Solution:
First, we need to move the x-term to the left side of the equation so we add 3x to both sides. Doing this gives us:

3x + y = 6.

Here, the coefficient of the x-term is a positive integers and all other values are integers, so we are done.
