    I assume that the equation is x+4y-4 = 0


    When we draw the graph for this equation, y-intercept is the point where the line crosses the y-axis. At this point, the x co-ordinate is zero. Therefore, substituting zero for x in the equation gives us the following:


    0+4y-4 = 0


    That is, 4y-4 = 0


    Therefore, 4y = 4


    y= 4/4 = 1


    The y-intercept is 1


    Please let me know if you have any questions.

    Did I do the problem right? Its been awhile!

    So sorry, I can't give you a correct answer, as I've been out of the loop too long  .Best to you!!

    Is your problem: y = x + 4y -4, And you're looking for the Y intercept?


    To solve for ( y ), we'll use ( 0 ) for(  x )   To solve for ( x ), we'll use ( 0 ) for ( y )          


      y =  x + 4y = 4  >  y = 0 + 4y - 4                 y = x + 4y - 4  >   0 = x + 4(0) - 4       


                                  -4y        -4y                                                 + 4                  +4


                                ----------------------                                ------------------------------


                                  -3y  =    -4                                                     4  =  x  > ( 0, 4 )


                                  -----      ------


                                   -3         -3


                                       y  =  1 1/3   >  ( 0, 1 1/3 )                               


           ""


                     


           Or, If your equation is like eggplant  >  x + 4y - 4 = 0


    Then to solve for (y), we'll use (0) for (x)     To solve for (x), we'll use (0) for (y)


          0 + 4y - 4 = 0                                                 x + 4(0) - 4 = 0


                      +4  +4                                                               +4  +4


    ------------------------                                        -----------------------------


                 4y  =  4                                                     x   =  4   >  (0, 4)


               -----    -----


                 4        4


                   y  =  1  >  (0, 1)                                                        


                                                                                         


                     ""

    All I can say is " WOW"!! An understanding, and graphics to boot!! Impressive!

    y= -x/4

    eggplant

    Your answer is wrong.
