Find the slope of the function in the table
Alex17521 [72]

Answer:

slope = -6

Step-by-step explanation:

slope formula: \frac{y2-y1}{x2-x1}

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)

\frac{12-0}{-2-0}

Simplify:

12 - 0 = 12

-2 - 0 = -2

\frac{12}{-2}=-\frac{6}{1}=-6

The slope of the function in the table is -6.
