Answer:
slope = -6
Step-by-step explanation:
slope formula:
To find the slope, take two points from the table(in this example I'll use points (0,0) and (-2, 12)) and input them into the slope formula:
(0, 0) = (x1, y1)
(-2, 12) = (x2, y2)
Simplify:
12 - 0 = 12
-2 - 0 = -2
The slope of the function in the table is -6.
