Step-by-step explanation:
This is an arithmetic sequence (graph is a line), so function:
a(n) = First term + (n-1) * Common Difference
Here First term = 42 and Common difference = 34 - 36 = -2 so

Answer B.

(2,10) (3,12) is ok, but (2,10) (2,12) is not.
Sorry if this doesnt make sense haha
Answer:

Step-by-step explanation:
The general equation of a line: 
In our case <em>a</em> is given

Now we plug in for <em>a</em> and we get:

Now we plug in our coordinates into this equation and we solve for <em>b</em>

So the equation of the line is
