Question

coleman graphed the relationship between the number of rotations of his front bike tire and the distance he traveled past a tree (in meters). 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 distance coleman traveled per tire rotation
b the number of tire rotations it took to travel 1 meter
c the number of tire rotations it took to be beside the tree
d none of the above

Explanation:

The y-intercept occurs when the number of tire rotations (x-value) is 0. On the graph, this is at (0, -10), meaning with 0 tire rotations, Coleman is 10 meters in front of the tree (negative distance = tree is in front). Option A describes the slope (distance per rotation), Option B is the reciprocal of the slope, and Option C refers to an x-intercept (when distance is 0). None of A-C match the y-intercept's meaning here.

Answer:

D. None of the above
