How do you change an equation of point-slope intercept to standard form?

The pint-slope intercept form of the equation of a line is: y = mx + b

The general form is: Ax + By = C. So,

y = mx + b subtract mx to both sides;

y - mx = b

-mx + y = b multiply by -1 to both sides;

mx - y = -b This is the general form.
