To find the equation of this line, we need to pick 2 points from the graph:

Now, we can use the extended point-slope form of a line to figure the equation of the line shown. The form is given as:

Let's plug in the 2 points we have taken, re-arrange, and find the equation:

We don't have this exact equation, but the closest is Equation B.
(this discrepancy might be due to the point we chose, they can be a little off from the grid).
Correct Answer
B
