Use the factor method and step by step
Answer:
Explicit form: 
Recursive form:
with
.
Step-by-step explanation:
The first term is 3 and we are dividing by 3 each time.
Another way to say we are dividing by 3 each time is to say we are multiplying by factors of 1/3.
If the first term is
and
is the common ratio then the geometric sequence in explicit form is:


The recursive form for a geometric sequence is
with
where
is the common ratio and
is the first term.
So the recursive form for our sequence is
with
.
Look at the coordinates and trace those points to a corresponding number on the x or y axis. Then write the first number in the coordinate in the x value and the second number for the y value, repeat the process for the rest of the points.
When you isolate the y on one side, the slope intercept form of the line is

Two plot point examples would be (0, - 3) (which is the y intercept) and (1, -7)
