Let's construct the equation in slope-intercept form. Start by finding the slope of the line.


(y-y)/(x-x)=(9-12)/(2-3)=(-3)/(-1)=3

This gives us y = 3x + b. Now, find b (or the y-intercept) by inputting a coordinate pair given in the table.


y=3x+b


9=3(2)+b


9=6+b


3=b

This gives us the completed equation of y = 3x + 3.

The correct answer is B) y = 3x + 3.
