    I am not certain of your question about this. I will be happy to critique your thinking.

    I just need to show the work from getting the equation 7x + 3y = 42 into slope- intercept form. Then I need the step by step work for graphing it in intercepts form.

    Your equation is perfect for finding intercepts.

    let x=0 , (put your little finger over the 7x term), then y = 14
    let y = 0, ( put your little finger over the 3y term), then x = 6
    so you have 2 nice points, (0,14) and (6,0)

    to change to slope-yintercept form
    3y = -7x + 42
    y = (-7/3)x + 14

    Thank you!

    1. 7X + 3Y = 42.
    Convert the std form Eq to the slope-interceptform:
    7X + 3Y = 42,
    3Y = -7X + 42,
    Y = -7/3X + 14, (Y = mx + b).
    Our 1st point will be at the Y-int
    where X is always 0.
    P1(0 , 14).

    Since our slope is neg. DECREASE
    b by 7:
    y = 14 - 7 = 7.
    X = 3 = The denominator of the slope.
    P2(3 , 7).

    GRAPH: P1(0 , 14) , P2(3 , 7)


    2. 7X + 3Y = 42
    At the y-int., X = 0.
    Calculate Y:
    7(0) + 3Y = 42
    3Y = 42
    Y = 14.
    P1(0 , 14).

    At the X-INT, Y = 0.
    Calculate X:
    7X + 3(0) = 42,
    7X = 42,
    X = 6.
    P2(6 , 0).

    GRAPH: P1(0 , 14) , P2(6 , 0).
