(x, y) = (3, 10), (__, 20)
if x = 3, the relation is not a function.
The gaps in the area needs to be closed so the data you use is lenient
7.2>0.9(n+8.6)
multiply 0.9 by all in parentheses
7.2> (0.9*n) + (0.9*8.6)
7.2> 0.9n + 7.74
subtract 7.74 from both sides
-0.54> 0.9n
divide both sides by 0.9
-0.6> n
ANSWER: -0.6> n
