    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?
