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. $y=\frac{1}{2}x+\frac{2}{5}$ $10(y)=10(\frac{1}{2}x+\frac{2}{5})$ $10y=5x+4$ $-5x+10y=4$ $5x-10y=-4$
