# How do you write y= -1 1/4x-3 1/4 in standard form?

May 14, 2015

The given equation is standard form is $5 x + 4 y = - 13$ .

Standard form for a linear equation is Ax+By=C.

$y = - 1 \frac{1}{4} x - 3 \frac{1}{4}$

Convert fractions to improper form.

$y = \frac{- 5 x}{4} - \frac{13}{4} = \frac{- 5 x - 13}{4}$

Multiply both sides by $4$.

$4 \cdot y = \frac{- 5 x - 13}{\cancel{4}} \cdot \cancel{4}$ =

$4 y = - 5 x - 13$

Subtract $5 x$ from both sides.

$5 x + 4 y = - 13$
