Answer:
D
Step-by-step explanation:
You want to identify the table showing direct variation between x and y.
Direct variation
If the relation is one of direct variation, the ratio y/x will be a constant. The sign of y will always match that of x, or will always be opposite. (Eliminates tables B and C)
The y/x ratios for table A are ...
3/1 ≠ 9/2
The y/x ratios for table D are ...
4/1 = 8/2 = 12/3
Table D shows direct variation.
