Answer:
None.
Step-by-step explanation:
The only possible restriction in the rational expression 
can originate in its denominator being zero for some values of a. However, since the denominator in this case (a^2+4) is always positive (and larger or equal to 4) for all values, no restrictions on the variable a exist.
Slope = 4/6= 2/3
Intercept is -1 (I think just check with gradient on graph in doing in my head)
Y=MX+B
Y=2/3X-1 ( if my calculations add up
Answer:
um I did this in my head but -20/3
Step-by-step explanation:
-6/5N × -5/6= 8× -5/6
simplify
n= 4/1× -5/3
n= -20/3
