f you have 3x+6y=27 how would you solve or y in slope intercept form
:
The slope intercept form: y = mx + b
:
Perform some simple algebra operations to get y on the left by itself, with a coefficient of 1:
:
3x + 6y = 27
:
6y = -3x + 27; subtracted 3x from both sides
:
y = -3%2F6x + 27%2F6; divided both sides by 6
:
y = -1%2F2x + 9%2F2; reduced the fractions
or
y = -.5x + 4.5, if you prefer decimals

The standard line formula (in slope, y intercept form) is:Y=mX+b where m=slope & b=y intercept.
-------------------------------------------------------------
3x+6y=27
6y=-3x+27
y=-3x/6+27/6
y=-x/2+27/6 answer.
You have a slope=-1/2 & a y intercept=27/6.
