From left to right the answers are: 16, 4, -8, -20

============================================

Work Shown:

y = -3x + 4

y = -3(-4) + 4 ... plug in x = -4

y = 12 + 4

y = 16

So x = -4 pairs up with y = 16

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

y = -3x + 4

y = -3(0) + 4 ... plug in x = 0

y = 0 + 4

y = 4

So x = 0 pairs up with y = 4

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

y = -3x + 4

y = -3(4) + 4 ... plug in x = 4

y = -12 + 4

y = -8

So x = 4 pairs up with y = -8

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

y = -3x + 4

y = -3(8) + 4 ... plug in x = 8

y = -24 + 4

y = -20

So x = 8 pairs up with y = -20

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

When plugging in x = -4, 0, 4 and 8, the y values that correspond are: y = 16, 4, -8, and -20 in that order.
