    Answer:

    An x-intercept of 2 implies

    (

    2

    ,

    0

    )

    is a point on the line

    A y-intercept of 4 implies

    (

    0

    ,

    4

    )

    is a point on a line

    The slope of the line joining

    (

    2

    ,

    0

    )

    and

    (

    0

    ,

    4

    )

    is

    #(Delta y)/(Delta x) = (4-0)/(0-2) = -2

    Using the slope-intercept form of the equation

    y

    =

    m

    x

    +

    b

    where

    m

    is the slope and

    b

    is the y-intercept

    we have

    y

    =

    2

    x

    +

    4
