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

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

    Which equates to
    $\displaystyle 2x+y=4$


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

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

    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?
