Answer:
A
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ] and we can use the points (0, 0) and (5, 30) to solve.
30-0/5-0
30/5
6/1
6
Now that we know what the slope is, we can eliminate C and D.
This means that he saves around $6 per week. With this being said, we can eliminate B as well.
Best of Luck!
