Question
The graph above shows the distance traveled d, in feet, by a product on a conveyor belt m minutes after the product is placed on the belt. Which of the following equations correctly relates to d and m?
- d = 2m
- d = m + 2
- d = 2m + 2
The correct answer is: d = 2m
y = mx + c can be used to relate d & m.
For co-ordinates (d, m) the equation can be written as d = sm + c
Thus d= sm
Slope =
