How do change slope-intercept form to standard form

Suppose you are given the slope-intercept form   y = 5x - 1/16 and are to change it to standard form.  Here's what you'd do:

1) multiply all 3 terms by 16 to eliminate the fraction 1/16:

16y = 80x - 1

Subtr. 16y from both sides:   0 = 80x - 16y - 1

This equation is in std. form.
