#### Answer

$5x-10y=-4$

#### Work Step by Step

The general form of a line is defined as $Ax+By=C$. First, multiply both sides of the equation by the least common denominator of all the terms. Then bring the $x$-term over to the left side of the equation.
$y=\frac{1}{2}x+\frac{2}{5}$
$10(y)=10(\frac{1}{2}x+\frac{2}{5})$
$10y=5x+4$
$-5x+10y=4$
$5x-10y=-4$
