Answer:

Explanation:
Given
Parallel to: 
Passes through (-9,-4)
Required
Determine the line equation
First, we calculate the slope (m) of the said line

Make y the subject

Divide through by 3

An equation has the general form:

Where

So:

Because the required line is parallel to
, then they have the same slope of 
Next, is to calculate the line equation using:

Where


This gives:


Open bracket


They give us informations about our ancestors and how did they live and what did they do and than compare it to present way's of life.
I believe the first one is 'physical geography' :-)
