Answer:
Step-by-step explanation:
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number
In this case a=5, and d=-2 so
a(n)=5-2(n-1) which can be simplified...
a(n)=5-2n+2
a(n)=7-2n
The domain is restricted to integers from 1 to +oo.
1.) y-7=4(x+3)
2.) y+7=(x-1)
3.) y-3=6(x+8)
