We will commonly see lines expressed in the standard form of a linear equation, especially when we look at and write systems of linear equations. The standard form of a linear equation puts the x and y terms on the left hand side of the equation, and makes the coefficient of the x-term positive. While standard form is commonly, we sometimes rewrite a line in slope-intercept form in order to graph it.
