Question 68130
rewrite each equation as a function of x

-3x+4y= 11

-3x+3x+4y=11+3x
4y=3x+11
{{{4y/4=(3x+11)/4}}}
{{{y=(3x+11)/4}}}  If you need to use function notation, replace y with f(x)
{{{f(x)=(3x+11)/4}}}
If this doesn't look exactly the way the book says that it should, it could also look like this:
{{{f(x)=(3/4)x+11/4}}}
