Rearrange each formula into standard form

I assume you mean to put each formula in the form $y=mx+b$

a) $y=\frac{2}{7}x-3$

$y=\frac{2}{7}x+(-3)$

b) $4.7y-0.03x=0.4$

$4.7y=0.4+0.03x$

$y=\frac{0.4+0.03x}{4.7}$

$y=\frac{0.03}{4.7}x+\frac{0.4}{4.7}$

$y=\frac{3}{470}x+\frac{4}{47}$

c) $6y=2-5x$

$y=\frac{2-5x}{6}$

$y=\frac{2}{6}-\frac{5}{6}x$

$y=-\frac{5}{6}x+\frac{2}{6}$
