When you plug those numbers into the equation, the answers are equal to or less than 8. The 'x' values are the numbers listed first in the ordered pair, the number following is the 'y' value.
Ones that will work
a.) (-6, 0)
(-6) + 3(0) ≥ -8
-6 + 0 ≥ -8
-6 ≥ -8
c.) (-5, -1)
(-5) + 3(-1) ≥ -8
-5 - 3 ≥ -8
-8 ≥ -8
e.) (-1, -2)
(-1) + 3(-2) ≥ -8
-1 - 6 ≥ -8
-7 ≥ -8
Ones that will not work
b.) (0, -3)
(0) + 3(-3) ≥ -8
0 - 9 ≥ -8
-9 ≥ -8
d.) (-16, 2)
(-16) + 3(2) ≥ -8
-16 + 6 ≥ -8
-10 ≥ -8
Hope this helps!
