Answers:
graph of line going through (0, 0) with a slope of 2
graph of line going through (0, 2) with a slope of 2
graph of line going through (0, 0) with a slope of 3
graph of line going through (0, 3) with a slope of 3

Answer 1

The graph with the line going through (0,0) with a slope of 2. This is because for every 1 hour, she has 2 bags of leaves.
The y number goes up by 2. 0 hours, 0 bags. 1 hour, 2 bags. 2 hours, 4 bags. And so on.
(0,0), (1,2), (2,4), (3,6)...
