Question 61794
y = 7x + 7       a) (?, 0)      b) (6/7, ?)    c) (0, ?)     d) (-6/7, ?)

a) y = 7x + 7                         
   -7 = 7x
   -1 = x
b) y = 7x + 7
   y = 7 (6/7) + 7
   y = 6 + 7
   y = 13
c) y = 7x + 7
   y = 7 (0) + 7
   y = 7
d) y = 7x + 7
   y = 7 (-6/7) + 7
   y = -6 + 7
   y = 1
