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 2, 1, 4, 7, 10.
What is the slope of the function?

–3
–2
3
4

Answer 1

3

Reason: For each increase of 1 in x, y increases by 3 (e.g., from x = -2 to -1, y goes from -2 to 1), so the slope is 3.
