Masja [62]

Answer:

The starting time.

Step-by-step explanation:

Since the graph represents Quinten’s distance from the start line as he runs a cross country race. And the x-axis represents the time, in hours, and the y-axis represents distance, in miles.

If the intercept is at y axis, it will represent the starting position. That is, the starting distance in miles.

But since the intercept is at x axis, the x-intercept represents the starting time in this situation.

The x-intercept will represent the starting time if the slope of the graph is positive, and represents the ending time if the slope of the graph is negative.
