    equation 4x - 7y = 84, find x and y intercepts for equation


    x-intercept is when:  y = 0


    y-intercept is when:  x = 0


    4x - 7(0) = 84  >  4x - 0 = 84  >  4x/4 = 84/4  >  x = 21   >  (21, 0) is the x-intercept.


    4(0) - 7y = 84  >  -7y = 84  >  -7y/-7 = 84/-7  >  y = -12  >  (0, -12) is the y-intercept.
