Answer

Table with 2 columns and 3 rows.Row 1: Column 1, 'x'; Column 2, 'y' Row 2: Column 1, '1'; Column 2, '3' Row 3: Column 1, '2'; Column 2, '1'

Table with 2 columns and 3 rows.Row 1: Column 1, 'x'; Column 2, 'y' Row 2: Column 1, '1'; Column 2, '1' Row 3: Column 1, '2'; Column 2, 'negative 1'

Table with 2 columns and 3 rows.Row 1: Column 1, 'x'; Column 2, 'y' Row 2: Column 1, '1'; Column 2, '2' Row 3: Column 1, '2'; Column 2, '2'

Explanation

A slope is the change in y divided by the change in x. In choice B, x increases from 1 to 2 while y increases from 4 to 6, so the slope is (6 − 4) ÷ (2 − 1) = 2, which is positive. The other tables have negative or zero slopes.
