If the equation is
$10x+5y=20$
Then

Divide both sides by 5.
$\frac{10x+5y}{5}=\frac{20}{5}$

Which equates to
$2x+y=4$

Subtract $2x$ from both sides
$-2x+2x+y=-2x+4$

Which equates to
$y=-2x+4$

Hi alysha,
Rearrange the given equation to the desired form

10x +5y= 20 so 5y=-10x+20 and y=-2x +4 form you want This equation is a straight line on coordinate paper. It has a slope of -2 and a y intercept of 4. Does this answer your question?
