    6x - 2y = 4


    Find x and y intercepts for equation


    x-intercept is when:  y = 0  >  6x - 2(0) = 4  >  6x = 4  >  6x/6 = 4/6  >  x = 2/3  >  (2/3, 0)


    y-intercept is when:  x = 0   >  6(0) - 2y = 4  >  -2y = 4  >  -2y/-2 = 4/-2  >  y = -2  >  (0, -2)


    Graph:  (2/3, 0)  (0, -2)

    Find the slope and y-intercept.


    6x - 2y = 4


    6x - 6x - 2y = -6x + 4


    -2y = -6x + 4  >  multiply each side by (-1). Note:  Y must be positive.


    2y = 6x - 4


    2y/2 = 6x/2 - 4/2


    y = 3x - 2    >   slope:  m = 3   y-intercept:  b = -2

    As you can see, the two graphs are the same.
