Question

The table represents a linear function.

A two column table with six rows. The first column, x, has the entries, negative 2, negative 1, 0, 1, 2. The second column, y, has the entries, negative 8, 2, negative 4, negative 10, negative 16.
What is the slope of the function?

–6
–4
4
6

Answer 1

Use two points that lie on the line, e.g. (0, -4) and (1, -10).

Slope = (y2 − y1)/(x2 − x1) = (−10 − (−4))/(1 − 0) = (−6)/1 = −6.

Answer: −6
