Converting Linear Equations in Standard form to Slope-Intercept Form (and vice versa)
Convert from standard form (Ax+By = C) to slope-intercept form (y = mx+b)
Start with the given equation
Add 7x to both sides
Simplify
Divide both sides by 8 to isolate y
Break up the fraction on the right hand side
Reduce and simplify
The original equation
(standard form) is equivalent to
(slope-intercept form)
The equation
is in the form
where
is the slope and
is the y intercept.
