Question

coleman graphed the relationship between the number of rotations of his front bike tire and the distance he traveled past a tree. negative distance means the tree is in front of coleman and positive distance means the tree is behind coleman. what does the y-intercept represent in this context? choose 1 answer: a) the number of tire rotations it took to travel 1 meter b) the number of tire rotations it took to be beside the tree c) the distance coleman traveled per tire rotation d) none of the above (chart: x-axis labeled distance past the tree (m), y-axis labeled tire rotations, with a line graph)

Explanation:

The y - intercept occurs when the x - value (distance past the tree) is 0. In this context, when the distance past the tree is 0, we are looking at the number of tire rotations when Coleman is at the tree (or beside the tree, since distance past is 0). Option A is about rotations per meter, which is the slope. Option B is also about a rate related to 1 meter, not the y - intercept. So the y - intercept represents the number of tire rotations it took to be beside the tree.

Answer:

B. The number of tire rotations it took to be beside the tree
