Answer:
2
Step-by-step explanation:
Well first put the table in ordered pairs.
(-3,18) (0,12) (3,6) (6,0)
Then well apply them in a graph. (graph below)
Now, use the slope formula to find the slope...
slope = y2-y1 / x2-x1 (take any two points; i'll pick the last two)
slope = 0 - 6 / 6 - 3
= -6 / -3 (to check; go to the graph and use the fraction as rise/run)
slope = 2
The line has a slope of 2.
