17. Fredward is buying juice and soda for his birthdayparty.  He wants to buy 12 total bottles and can spend$29.  If juice cost $3 per bottle and soda cost $2per bottle, how many bottles of each should he buy?
Fredward should buy              bottles of juiceand              bottles of soda for his birthday party.
j + s = 29    j + s = 12
j = 3
    s = 2
3j + 2s = 29      j + s = 12
3j = 29
    2s = 12
18. Select which solutions workfor this system:

(-3, 8)
(-4, 2)
(2, 4)
(2, -3)
(-1, 4)
(-3, 1)
(-3, 3)
(0, 5)
19. Match each equation to its corresponding graph:
a.  y > -x - 2
     y < -5x + 2

b.  y < -x - 2
     y > -5x + 2

c.  x < -3
     y < 5x + 2
           3

d.  y < 1x + 2
