Answer: The 2nd choice.
Step-by-step explanation:
The y-intercept is the y coordinate when x = 0. Based on the table, we can see that the y coordinate is 12 when x is 0.
The slope is equal to (y2-y1)/(x2-x1) for any given points (x1,y1) and (x2,y2).
We can choose the point (0,12) to represent (x1,y1) and the point (6,0) to represent (x2,y2).
Therefore, the slope is (0-12)/(6-0) = -12/6 = -2
